The Late Show has some suggestions to spice up the Democratic presidential debates.

"Tonight was the last debate before Democratic voting begins in February," and "for the first time in the election cycle, the Democrats had an all-white debate stage," Stephen Colbert said on Tuesday's live Late Show. "Once again, J.Lo. was robbed." Former Vice President Joe Biden "admitted he was wrong" to vote to authorize the Iraq War, and Sen. Bernie Sanders (I-Vt.) "provided some historical context," he said, and he ribbed Sen. Amy Klobuchar (D-Minn.) for flubbing her "local example of women succeeding in politics."

But "the big story heading into the debate tonight was the falling-out between Bernie Sanders and Elizabeth Warren," Colbert said. It flared up over a disagreement on whether Sanders told Warren a woman can't win the White House in 2020, and "when Bernie was asked about it" at the debate, he "categorically denied the charge." Asked to respond, "Warren brought down the hammer," he said, joking that the men on stage had collectively lost more than 10 elections after her answer.

"To a lot of young Democrats, the beef between Bernie and Warren must feel like seeing your parents getting divorced" or "R2-D2 and C3PO become enemies," Trevor Noah said at The Daily Show. "Bernie was sticking to his story that he never said a woman can't be president," and Warren shot back that "maybe none of these men could be president," he marveled. "Not since Kill Bill have I seen one woman obliterate that many men in one fell swoop."

Warren "definitely won this exchange, although it would have been a much cleaner victory if she didn't come back a few moments later to create one of the weirdest moments we've ever seen in a debate," Noah said, showing her and Bernie's "unnecessary, nitpicky" fight over whether 1990 was 30 years ago. "It felt like we were watching an old couple fight in a diner."

But "other than what we just saw, there wasn't much new in this debate," Noah said. "They touched on health care, trade policies, impeachment, and to be honest, it was more of the same ... All in all, today's debate wasn't that exciting. And I guess this is what happens when you only have white people at your party." He ended with a devilishly clever strategy for Mike Bloomberg.

President Trump is heavy on the plans and light on the specifics.

In a wide-ranging interview with The Wall Street Journal on Tuesday, Trump confirmed he was considering adding more countries to his travel ban, said he would impose tariffs on European automobiles, and added he was working on a middle-class tax cut. Not that he said which ones, when that would happen, or just what the cut entailed, respectively.

Reports first indicated the Trump administration was planning an addition to its travel ban earlier this month. Trump told the Journal his administration does have plans to add more countries to the list later this month, but wouldn't say more. He also said his administration is "looking at many different things" when it comes to his longstanding — and now faded — push to oust Venezuelan leader Nicolás Maduro.

Trump went on to say he's still working on a trade agreement with the EU, saying "I'm going to put tariffs on them if they don't make a deal that's a fair deal." He was asked when that would happen but didn't answer, just saying "they know what the deadline is." And as for policies back in the U.S., Trump said "we're talking a fairly substantial… middle-class tax cut" that'll be revealed in 90 days. The plan's implementation dependent on him being reelected, Republicans holding the Senate, and the GOP taking back the House — the third bit being very unlikely in a presidential election year.

The Wuhan virus, which broke out in China last month and has so far infected more than 300 people and killed six, has reportedly reached U.S. shores, a federal source told CNN.

The Centers for Disease Control and Prevention is expected to announce Tuesday that a person in Washington state has been infected, making the U.S. the sixth country to experience the outbreak of the respiratory illness, along with China, Taiwan, Japan, Thailand, and South Korea. The patient was hospitalized with pneumonia last week after having traveled to eponymous Wuhan, China, where the outbreak appears to have originated at a seafood and poultry market, The New York Times reports.

A lot remains unknown about the virus, although the latest development strengthens the hunch that it spreads from person to person. One of the most pressing questions, Dr. William Schaffner, a professor of preventative medicine and infectious diseases at Vanderbilt University Medical Center, told the Times, is how frequent that human-to-human transmission is.

Ozzy Osbourne has revealed he's battling Parkinson's disease, opening up about his diagnosis in an emotional new interview.

The rock star spoke in an interview with Good Morning America that aired Tuesday, saying he was diagnosed with a form of Parkinson's disease after a fall last year.

"It's been terribly challenging for us all," Osbourne said, though his wife, Sharon Osbourne, described the diagnosis as "not a death sentence by any stretch of the imagination."

Osbourne previously postponed his planned 2019 tour dates, citing his health. "Words cannot express how frustrated, angry and depressed I am not to be able to tour right now," he said at the time. He reiterated to GMA that he "can't wait" to get back on the road again. "That's what's killing me," he said. "I need it, you know."

Now that he's revealed his diagnosis, Osbourne told GMA "I feel better," adding he hopes his fans "hang on and they're there for me because I need them." Osbourne, who's set to release a new album Ordinary Man next month, also promised, "I ain't going to go anywhere yet." Brendan Morrow

The just-starting Senate impeachment trial of President Trump has resurfaced reminders of what isn't allowed in the room where it happens: talking, electronics, questions from the press, among other things. And while it's true that coffee and other non-water drinks are always barred from the Senate floor, Sen. Rick Scott (R-Fla.) has just generously reminded us that another liquid will be available for slurping come trial time.

Yes, because one senator desperately needed a dose of dairy back in 1966, milk is allowed on the floor along with water. No senators have broken out the dairy this impeachment around, but keep an eye on Vermont Sens. Bernie Sanders (I) and Patrick Leahy (D), who've been spotted sipping milk together on special occasions for decades. Kathryn Krawczyk

Gallup revealed Tuesday that President Trump's approval rating during his third year in office set the record for the biggest partisan gap since the pollster began its records.

Republicans and Democrats are dramatically split — 89 percent of Republicans think Trump is doing a good job, compared to just 7 percent of Democrats. That 82-point difference is the largest ever, beating out the 79-point margin following Trump's second year in office. But what about the third subset, those pesky independents?

Trump's numbers don't crater among independents like they do with Democrats, and have improved over the last year — his 38 percent approval rating among non-affiliated respondents is higher than his 35 percent average rating to date, but they're still historically low. In the post-World War II era every other president has reached the 40 percent threshold among independents, with the lowest mark going to Jimmy Carter's 42 percent.

Overall, Trump checked in with a 42 percent approval rating during year no. 3, an uptick from his first and second years. It's not far behind the numbers averaged by former presidents like Barack Obama and Ronald Reagan at this point in their tenures, but it's still one of the lowest three-year averages during a first term since World War II. Only Carter's 37.4 percent trails. The poll was conducted over the phone from a random sample of 4,560 adults living in the U.S. by Gallup between Oct. 14, 2019 and Jan. 16, 2020. The margin of error is 2 percentage points. Read more at Gallup.

Prosecutors in Brazil have charged journalist Glenn Greenwald with cybercrimes, The New York Times reports.

The American journalist last year began publishing a series of stories at The Intercept that, as Columbia Journalism Review wrote, "sent shocks through Brazil" by appearing to show "that Sergio Moro, Brazil's justice minister and the former top judge in a major corruption investigation, colluded with federal prosecutors to convict prominent political figures." The Intercept said its reporting was based on "private chats, audio recordings, videos, photos, court proceedings, and other documentation" that was "provided to us by an anonymous source."

Brazilian prosecutors have now charged Greenwald "for his role in the spreading of cellphone messages that have embarrassed prosecutors," the Times reports. Prosecutors in a complaint claimed Greenwald is part of a "criminal organization" that hacked prosecutors' and other officials' cellphones.

The Intercept co-founder Jeremy Scahill on Twitter called these charges "despicable, dangerous and a crime against journalism," and others journalists quickly spoke out in Greenwald's defense.

"Regardless of your personal feelings about Glenn, this is a regime with deep authoritarian tendencies personally targeting a critical journalist," Vox's Dylan Matthews tweeted. "It's a horrendous abuse of power that everyone should denounce."

Greenwald in a statement to The Daily Beast said he "did nothing more than do my job as a journalist — ethically and within the law," calling the charges "an obvious attempt to attack a free press in retaliation for the revelations we reported about Minister Moro and the Bolsonaro government." He added, "We will not be intimidated by these tyrannical attempts to silence journalists. I am working right now on new reporting and will continue to do so." Brendan Morrow
