Investigators still do not know why Stephen Paddock shot and killed 58 people during an outdoor music festival in Las Vegas last October, CBS News reports. In a press conference Friday, authorities conceded that three months of investigation had not yielded any findings on Paddock's motivations, though Clark County Sheriff Joe Lombardo did emphasize that Paddock acted alone and that his girlfriend — who was at one point suspected of helping him — would not be charged with any crime.

During the press conference, Lombardo also discussed a newly released 81-page report that examined Paddock's actions in the months leading up to the shooting, which was the deadliest in modern American history. The evidence indicated Paddock had been planning an attack for a while; investigators found he purchased over 50 firearms in the 12 months leading up to the shooting, and that he had studied the response strategies of various law enforcement departments.

Lombardo noted that "disturbing" internet searches Paddock had conducted indicated he may have considered carrying out the attack at other concerts or at beaches in California, CBS News reported. Investigators also found child pornography on Paddock's computer.

"Like all of [President] Trump's closest relationships, his relationship with Twitter is sort of a love-hate situation," Trevor Noah said on Wednesday's Daily Show. And on Tuesday, Trump invited Twitter CEO Jack Dorsey to the Oval Office to complain. "That's right, my friends, the president of the United States is upset because he feels he should have more Twitter followers," Noah said. "This is absolutely ridiculous. Like, what's next? He's going to complain to Instagram because his thirst traps aren't blowing up?"

Trump flying in the CEO of Twitter to complain about losing followers will actually probably "inspire more people to run for office," Noah suggested. "People are going to be on stage, like, 'I'm running for president so that I can ask Jeff Bezos: What happened to my tube socks, which were supposed to be here by Wednesday?!'" He pitied "everyone in this meeting with Trump who had to sit there and take it seriously," including Dorsey, forced to "explain to a president that some of his followers were deleted because they were bots and spam accounts."

"Twitter is only one of the president's beefs right now," Noah said. He's also feuding with the media, House Democrats, and the Constitution, threatening to "head to the Supreme Court" if Democrats impeach him. "Just to be clear, that's not a thing," Noah said. "The Supreme Court can't overrule an impeachment. ... This would be like if a cop gives you a ticket and your response is: 'I'm fighting this, buddy — you'll be hearing from my orthodontist!'"

"So in the last 48 hours, the president has gotten in fights with Congress, the press, and Twitter," he said. "Look, we can't help him with the first two, but we do have someone who can help him out online." That would be Jaboukie Young-White, and you can watch him advise Trump to seem less thirsty on Twitter below. Peter Weber

President Trump made some promises during the 2016 campaign: He would release his tax returns, "build the wall," "drain the swamp," protect Medicare and Social Security, and champion law and order, to name a few.

Like all presidents, he has been pretty selective about which campaign promises merit follow-through. The "wall", for example, was worth shutting down the government and sparking a constitutional crisis; his tax returns were deemed worthy of going to court and threatening a constitutional showdown to keep hidden. One of the "promises" he has tried to keep, according to Special Counsel Robert Mueller's report, is "lock her up," his enduring campaign chant about 2016 rival Hillary Clinton.

Mueller's report "brimmed with examples of Mr. Trump seeking to protect himself from the investigation," The New York Times reports, but it also shows at least three instances of him "trying to wield the power of law enforcement to target a political rival, a step that no president since Richard M. Nixon is known to have taken." As with many potential crimes Mueller records, Trump's orders or suggestions to prosecute Clinton were apparently ignored or redirected by former Attorney General Jeff Sessions and former White House Counsel Don McGahn.

Still, Trump's attempt to target Clinton "reeks of a typical practice in authoritarian regimes where whoever attains power, they don't just take over power peacefully, but they punish and jail their opponents," political historian and professor Matthew Dallek tells the Times. It appears from Mueller's report that Trump, encouraged by his Fox News allies, didn't appreciate the difference between political self-preservation and weaponizing the law enforcement tools he seems to think work for him, adds Duke University law professor Samuel W. Buell. "All of his demands fit into a picture that he believes the apparatus is mine"

George Conway was, by all accounts, happy when his wife, Kellyanne Conway, helped campaign-manage President Trump into office. But that was so 2016. Since then, Conway has become one of Trump's loudest conservative critics, to the consternation of his wife, who is one of Trump's top White House aides and most ardent defenders in the media.

When Trump's 2016 rival, Hillary Clinton, wrote an op-ed in The Washington Post on Wednesday night, arguing that Vladimir Putin is trying to make Russia great again by attacking U.S. democracy and Congress needs to hold Trump accountable for aiding him, using Special Counsel Robert Mueller's newly released report as a road map, George Conway repurposed Clinton's 2016 slogan: "If she's with the Constitution, I'm with her. "

Soon after Katie Pollak adopted her dog Chipper seven years ago, she discovered that he wasn't obsessed with traditional toys, but rather with discarded plastic water bottles they would find while out on walks and hikes.

"He started picking them up immediately, so I encouraged it and rewarded it," Pollak told Today. "And he motivated me to do the same. I really started getting out and picking up more than I was before, so we created kind of a team."

Pollak and Chipper, now 8, live in Mesa, Arizona, and enjoy spending time outdoors. Pollak carries garbage bags with her every time they go hiking or paddleboarding, and together, they pick up recyclables, including cans and bottles, and trash, like old clothes and wrappers. They have filled countless bags, and often meet with friends to clean up spaces across Mesa. Chipper, Pollak said, "reminds me all the time to be my best self and do everything I can, and he's so much fun to do it with." Catherine Garcia

Mohammad Yusuf Ibrahim, a politically connected millionaire spice trader, has been detained in connection with the coordinated suicide bombings that killed more than 350 people on Easter Sunday, Indian officials told The New York Times.

Indian media reports that two of Ibrahim's sons were among the eight suicide bombers, and during a raid at his villa near the Sri Lankan capital Colombo on Sunday, a female suspect detonated a suicide vest, killing herself, two of her children, and several police officers. Ibrahim is now being interrogated by police, investigators said.

The Islamic State has claimed responsibility for Sunday's attacks, but Sri Lankan officials said they do not know how the bombers are linked to the terrorist group. During a press conference on Wednesday, Sri Lanka's minister of defense, Ruwan Wijewardene, said most of the bombers were well-educated and from families that "are stable financially."

Now that Special Counsel Robert Mueller's redacted report has been released, some people are demanding President Trump's impeachment while others say there's no need to act, but there is a middle ground, Hillary Clinton writes in an op-ed published Wednesday night by The Washington Post.

The Mueller report's "definitive conclusion" is simple, Clinton said: The 2016 presidential election "was corrupted, our democracy assaulted, our sovereignty and security violated." History has shown a way forward from here, she said, and that involves Congress holding "substantive hearings" and forming an independent and bipartisan commission to "help protect our elections."



Clinton admits that the matter is "personal for me, and some might say I'm not the right messenger," but while serving as a senator and secretary of state, she said, she saw the ascent of Russian President Vladimir Putin, and "knows firsthand that he seeks to weaken our country." Congress must take the Mueller report and use it "as a road map," she writes. "It's up to members of both parties to see where that road map leads — to the eventual filing of articles of impeachment, or not."

Along with hearings that "build on the Mueller report and fill in its gaps, not jump straight to an up-or-down vote on impeachment," Clinton argues, a commission like the one created after the 9/11 attacks is necessary because "the president of the United States has proved himself unwilling to defend our nation from a clear and present danger."

She also has a message for House Democrats, reminding them that during Watergate, Congress was able to pass the Endangered Species Act, Federal-Aid Highway Act of 1973, and War Powers Act. "Stay focused on the sensible agenda that voters demanded in the midterms, from protecting health care to investing in infrastructure," Clinton advised, as it's "not only possible to move forward on multiple fronts at the same time, it's essential."
