Three Chicago police officers investigating suspected narcotics sales were shot Monday night, authorities said.

Their injuries are not life-threatening, department spokesman Anthony Guglielmi said. Four officers were in the Homan Square neighborhood when they encountered a man and woman in a "known drug area," Guglielmi said. The man ran and opened fire at the officers, hitting three of them, the Chicago Sun-Times reports. One officer returned fire, and the man was hit and killed, Guglielmi said. A witness told the Sun-Times that while it's not unusual to hear gunshots in the neighborhood, it's been "fairly quiet" over the past few months. Catherine Garcia

Donald Trump and Hillary Clinton are meeting in their first of three presidential debates on Monday night at New York's Hofstra University, and with the race neck and neck, the stakes are very high. The 90-minute debate, moderated by NBC Nightly News anchor Lester Holt, takes place amid a heated debate over whether the moderator should call out gross factual inaccuracies from either candidate — the Clinton camp says yes, the Trump side says no. Clinton has been studying Trump's temperament as well as the issues, and Trump's campaign says the Republican nominee has been largely eschewing normal debate preparations.

The debate begins at 9 p.m. Eastern time, and will be broadcast on PBS, ABC, NBC, CBS, and Fox, plus C-SPAN, CNN, Fox News, and MSNBC. Facebook and Twitter, as well as several other websites, will also livestream the debate. And if you want to prepare by boning up on every debate since 1960, PBS Newshour has an interactive site at the ready. An estimated 100 million people are expected to tune in to the debate. You can get a sense of Holt's task Monday night in the CNNMoney preview below. Peter Weber

Everyone, it seems, has advice for what Hillary Clinton and Donald Trump should do in their first presidential debate on Monday. But one intrepid expert at the University of Michigan has already compiled a new book on debating Trump, just 18 months into Trump's political career. In 11 Republican primary debates, Trump stood on stage for almost 24 hours total and spoke for a combined 3 hours, 20 minutes, and 7 seconds, and that record "gives insights into how he could deal with Clinton, and she can deal with him," Aaron Kall, director of debate at the University of Michigan and editor of the new book Debating the Donald, told USA Today.

One-on-one presidential debates are different than the multi-candidate primary debates Trump has participated in so far, but Kall and other debate experts say that Trump will likely carry some of his tactics to his first Clinton debate at Hofstra University in New York. Some examples include deploying devastating one-liners especially if Clinton attacks him, using his unpredictably to his advantage, talking directly to the TV audience, subtly belittling Clinton through interruption and calling the former senator and secretary of state "Hillary," and claiming he won the debate no matter what happens.

You can find examples of each of those tactics at USA Today, and reporter Rick Hampson sums up the collective wisdom for Clinton: "Don't hit unless you're ready to be hit; steer the debate toward detailed (and possibly boring) policy discussions; control the clock if you don't want Trump to; and watch out if he tells you how good you look."

The first presidential debate is Monday night, "and more than 100 million people could be watching two candidates whose campaigns have been defined less by questions about their policies than their ethics," John Oliver said on Sunday's Last Week Tonight. Previous presidential campaigns have had their scandals, "but this campaign, the scandals have been so pronounced, polls show that less than half the electorate sees either candidate as honest or trustworthy. And you may not like either candidate for good reasons, but if you are still somehow torn about which one to vote for and are factoring their scandals into your decision, we thought it might help to spend tonight walking you through them."

He started with Hillary Clinton. Not all his viewers will be happy about digging through Clinton's closet, Oliver conceded, but "not being as bad as Donald Trump is a low bar to clear, and if you focus on nothing but him, you fail to vet a woman who may be president." There are plenty of silly outrages and phony scandals on the internet, "but many rational people are still worried about two scandals," the emails and the Clinton Foundation, he said. Oliver ran through what we know about each, then said, "Look, we've spent several frustrating weeks trawling through all the innuendo and exaggeration surrounding her email and foundation scandals, and the worst thing you can say is: They both look bad, but the harder you look, the less you actually find. There's not nothing there, but what is there is irritating rather than grossly nefarious." That brought him to Donald Trump.

"If you are struggling with the idea of voting for Hillary because of all this, you need to take a long, hard look at Trump," Oliver said. "If you're irritated by her lying, that is understandable, but he's quantifiably worse." There's his refusal to release tax returns, sprawling global business empire, and the Trump Foundation. "And the thing is, we have barely scratched the surface of his scandals — there is everything," Oliver said. He wrapped up with an analogy comparing raisins and ethical failings, but first laid out his bottom line: "This campaign has been dominated by scandals, but it is dangerous to think that there is an equal number on both sides. And you can be irritated by some of Hillary's — that is understandable — but you should then be f--king outraged by Trump's."

In Hollywood, even the animal actors shave a couple of years off their real ages, and new legislation will help keep the actual DOBs of stars under wraps.

On Saturday, California Gov. Jerry Brown (D) signed legislation that requires online subscription entertainment database sites, like IMDb, to remove the age of an actor if asked; the site will have five days to follow through with the order. Opponents say removing accurate age information from the websites stifles free speech, Variety reports, but the bill's sponsor and actors, including SAG-AFTRA President Gabrielle Carteris, believe it's a necessary move to prevent age discrimination, rampant in Hollywood.

Before Brown signed the bill, Carteris urged SAG-AFTRA members to reach out to the governor to push him into backing the bill, writing that an actor's age being published on a site used for casting causes "career damage." After the legislation was signed, Carteris said in a statement the bill will help actors secure "a fair opportunity to prove what they can do." Age wasn't a factor when it came to Carteris' most famous role as intense newspaper editor turned unexpected young mother and wife Andrea Zuckerman on the 1990s hit Beverly Hills 90210; she was 29 years old when she first started playing a 16-year-old.

Monday night is the highly anticipated first presidential debate between Hillary Clinton and Donald Trump, and on Sunday night, Fox News contributor Charles Krauthammer — a fan of neither candidate — gave his unsolicited advice to both on Megyn Kelly's Kelly File. He started with Trump, advising that "between now and tomorrow night, decaf only, don't talk about your hands, and in the end, think of yourself in the press conference with the president of Mexico." Kelly pointed out that Trump drinks neither alcohol nor caffeine, so no coffee, and Krauthammer said, "He's off on the right foot."

"Your job in this debate is to make people look at you and think you're a plausible president," Krauthammer said to Trump, and viewers "won't appreciate snarkiness or disrespect," as in the GOP primary debates. Trump's goal isn't to "win on points, not to win on substance," but "to show himself to be calm," he added, which means first and foremost "not shout."

With Clinton, on the other hand, "I think what she needs to do is jab," Krauthammer said, "not to go for the haymaker, not to go for the one thing that's going to knock him out. He's very good a rope-a-dope and slipping away — you see, all the metaphors are boxing, because this really is a spectacle of boxing." In that vein, what Clinton "needs to do is the flurries, in other words to attack him on many points, calmly but one after another. I'm sure at some point he's going to want to succumb and strike back, and that's her opportunity." What if the debate is boring? Kelly asked. "Boring, he wins." Krauthammer said. "If he can be up there for 90 minutes and be dull, he wins the debate." "I'm excited to see them be dull," Kelly said. "I don't care." Watch below. Peter Weber

Ohio's method of removing voters from the registration rolls after six years of not voting was ruled unconstitutional Friday by a federal appeals court.

A lawsuit filed by the ACLU of Ohio and Demos, a public policy organization, asked that the controversial "supplemental process" come to a halt and the thousands of people kicked off the rolls but still eligible to vote be reinstated. They argued that this November, it's likely people who don't vote as often will hit the polls, and the process violates the National Voter Registration Act, which says states are only able to remove voters from the rolls if they request it, move, or die. Secretary of State Jon Husted says Ohio removes voters from the rolls to prevent fraud and keep the rolls current.

In June, ABC News reported many of the voters taken off the rolls lived in low-income neighborhoods or areas that typically voted Democrat. On Friday, the Sixth Circuit Court of Appeals reversed a lower court decision in favor of Husted, who said in a statement he was "frustrated" by the ruling that "overturns 20 years of Ohio law and practice, which has been carried out by the last four secretaries of state, both Democrat and Republican." Mike Brickner, senior policy director of the ACLU of Ohio, said he is hopeful that a "plan will emerge soon to allow the tens of thousands of voters illegally purged from the rolls to vote in the upcoming presidential election."

Donald Trump's campaign manager, Kellyanne Conway, was on ABC's This Week Sunday morning, and host George Stephanopoulos asked her about Monday night's debate, the role of debate moderators, whether Trump would apologize for his "birther" crusade ("that's a very personal thing"), and President Obama's response to Trump's assertion that "our African American communities are absolutely in the worst shape they've ever been in before. Ever, ever, ever." On Friday, Obama told ABC News: "I think even most 8-year-olds will tell you that whole slavery thing wasn't very good for black people. Jim Crow wasn't very good for black people."

"So are African American communities really in the worst shape they've ever been?" Stephanopoulos asked. "Seems to me that everything that Donald Trump is saying — and it's too bad that the president is so glib about these issues," Conway said, and Stephanopoulos jumped in: "The president's glib about race issues?" "No, no, no," Conway said, "he was very — he — no, George, he was just very glib about what the — you know, calling — referring to an 8-year old." Trump wants to rebuild inner cities, "tackling full-on poverty and joblessness and homelessness in the inner cities and crime," especially in Chicago, she said. "And we're not going to have a serious conversation about crime in the inner cities?"

Obama, of course, has been having that conversation for years, even if Trump has not been a part of it, but Conway said she thinks "Donald Trump should also be applauded for actually trying to make a difference in these communities." On the debates, Conway said that she thinks all the moderators will be great, including NBC's Lester Holt, but "I really don't appreciate campaigns thinking it is the job of the media to go and be these virtual fact-checkers and that these debate moderators should somehow do their bidding." When Stephanopoulos asked about Trump's big lead over Clinton in documented lies, Conway said that polls show voters trust Trump more than Clinton.

"I can understand why the Clinton camp is very nervous, because Donald Trump's got great presence, stature, he's a brilliant debater," Conway said. "Newt Gingrich put it best. The former speaker recently said Donald Trump is the best debater he's ever seen, he's like the Babe Ruth of debating, he shows up and swings does a great job." When Stephanopolous asked about Trump's suggestion he would invite purported former Bill Clinton mistress Gennifer Flowers to the debate, since rescinded, Conway said that Trump "wants to remind people that he's a great counter-puncher. They started this one by saying they would give a front-row seat to Mark Cuban — who by the way, until very recently very favorable toward Donald Trump and his candidacy." Despite Trump's tweet, Flowers "has not been invited by the campaign," Conway said. "She has a right to be there if somebody else gives her a ticket." Peter Weber
