Vaccines work, and Twitter wants you to know it.

Amid growing misinformation surrounding vaccines, Twitter has rolled out a tool that combats falsities with reliable information, it announced Friday. The tool drops a link to vaccines.gov at the top of U.S. searches for tweets related to vaccines, and links out to appropriate government information for Canada, Japan, Brazil, and several other countries.

In the past few months, the U.S. has seen the number of measles outbreaks skyrocket, putting it on track for the highest annual number of measles cases since the disease was declared "eliminated" in 2000. That's partially been furthered by people who choose not to vaccinate themselves or their children, and who often chalk their decisions up to false associations between vaccines and autism. Conspiracy theorists and even the president have spread this misinformation, and it has proliferated widely on social media as well.

That's why Twitter on Friday quietly unveiled its small addition to its search function, which puts reliable information on top of anything questionable. Twitter also said it won't "auto-suggest queries that are likely to direct individuals to non-credible commentary and information about vaccines" in its blog post. It already works to ensure advertisements don't "contain misleading claims about the cure, treatment, diagnosis, or prevention of certain diseases and conditions," the post continues.

The move is similar to how Twitter offers resources when someone searches for tweets related to suicide or self-harm. It also has a reporting feature so users can notify a team that reviews mentions of self-harm or suicide on the site. Kathryn Krawczyk

"Right now, the Democratic Party has an option for everyone," Trevor Noah said on Monday's Daily Show. "There's moderates, there's progressives, there's X-Men, and there's even a guy who's worth $1.6 billion. But what if $1.6 billion just isn't rich enough for some voters? Well then, those people might be in luck." That's because billionaire former New York City Mayor Michael Bloomberg "is on the verge of jumping into the Democratic primary, because he doesn't think any of the current candidates can beat Trump," he said. "And you have to admit, that's such a billionaire thing to do."

"Bloomberg may be making a fashionably late entrance into the presidential race, and his fellow Democrats aren't exactly giving him a warm welcome," Noah said, with a special laugh for Sen. Bernie Sanders' (I-Vt.) reaction. So why is Bloomberg running? Reportedly, "Jeff Bezos told Bloomberg to run," he said. "You know you're rich when the Amazon guy orders something from you! That's money."

"Wow, he just ordered up a presidential candidate — what level of Amazon Prime is that?" Seth Meyers echoed at Late Night. "Bloomberg's interest in running and Bezos' prodding come after weeks of billionaires freakouts over the possibility that someone who's critical of big banks and Wall Street like [Sen. Elizabeth] Warren or Bernie could get the Democratic nomination. In fact, last week even Bill Gates expressed concern about how much he personally would have to pay in taxes and joked that he might not have that much left over." Warren trolled Bloomberg and Gates with their own internet calculators for billionaires.

"In reality, the vast majority of Democratic primary voters say in polls that they're actually satisfied with the choices they already have," Meyers said. "People aren't just mad at billionaires out of jealousy or because candidates demonize them. There are real-world examples that are informing people's doubts that the wealthy can solve everything," or anything. Watch below. Peter Weber

The House's public impeachment hearings start Wednesday, and President Trump appears determined to bury them under a blizzard of tweets and obfuscation, Jimmy Kimmel said on Monday's Kimmel Live. "You know, people thought it was magnanimous when he decided not to take a presidential salary. Turns out it's because he doesn't do any presidential work. He's tweeting all day."

Trump is releasing a transcript Tuesday from an earlier call with Ukraine's president, Kimmel shrugged. "What he thinks this will prove, I have no idea. Just because you release a transcript of a second call where you didn't break the law doesn't mean you're off the hook for the first. ... The president is also ramping up his attacks on the whistleblower. This is his thing now, attacking the whistleblower. 'Never mind what I did — get the guy who told people I did it!'"

"Today we learned that another Pentagon official testified that Trump himself withheld aid money to Ukraine because he wanted an investigation of Joe Biden," Kimmel said. "That was damaging," but the White House is most worried about former National Security Adviser John Bolton and his copious notes. Meanwhile, Trump announced "he's thinking about making a trip to Moscow for a May Day parade," Kimmel sighed. "The idea that the president of the United States would go to Russia to celebrate their military might is absurd, and no one was more surprised than Joe Biden."

"Oh hey, speaking of people Donald Trump doesn't want to see: It was a rough weekend for Donald Trump Jr," Kimmel deadpanned. "DJTJ was here at UCLA promoting his new book, and he was heckled by what he thought was a group of liberals. Turned out it was a group of angry far-right-wingers who were upset there'd be no Q&A. And Don Jr., to his credit, stepped aside and let his girlfriend, Kimberly Guilfoyle, handle the yellers for him." Watch below. Peter Weber

Mexico flew former Bolivian President Evo Morales to Mexico City on Monday after offering him asylum amid what Morales and his supporters call a "coup" and protesters call a restoration of democracy in Bolivia. Morales resigned Sunday after weeks of protests following a controversial election in late October that international observers flagged for irregularities; the final straw was the country's military chief Gen. Williams Kaliman calling on him to step down to restore peace to Bolivia.

With Morales gone and all other officials in the line of succession also tendering their resignations, Bolivia has no clear leader. "It hurts me to leave the country, for political reasons, but I will always be concerned," Morales tweeted. "I will return soon, with more strength and energy." Mexican Foreign Relations Secretary Marcelo Ebrard tweeted a photo of Morales on the Mexican Air Force plane, explaining that "according to current international conventions, he is under the protection of Mexico. His life and integrity are safe."

The weeks of massive protests against Morales were sparked by the Oct. 20 election, in which he sought a fourth term despite constitutional term limits and a referendum that upheld those limits; a friendly top court later threw out the restrictions. Morales also declared victory before official results were in, and no results were released for 24 hours. Organization of American States election observers found a "heap of observed irregularities" in the election and called for a new vote. Morales had served since first winning the presidency in 2006, becoming Bolivia's first indigenous president. He leaves a legacy of increased economic equality, a long streak of stability, and accusations of corruption. Peter Weber

President Trump had some encouraging words for Sean Spicer on Monday night after his former press secretary was voted off Dancing With the Stars.

But they weren't Trump's first words of encouragement for Spicer on Monday — as he had before, Trump encouraged his Twitter followers to "vote for Sean Spicer on Dancing With the Stars. He is a great and very loyal guy who is working very hard. He is in the quarterfinals — all the way with Sean! #MAGA #KAG" After Spicer got the boot, Trump deleted that tweet.

"It's a minor thing but nonetheless telling that Trump deleted his tweet promoting Spicer," Washington Post columnist Daniel Drezner tweeted. "It's almost as if he can’t abide the fact that his endorsement lacks sufficient power." Other people saw a pattern with the people Trump endorses:

But Spicer probably had Trump — or at least Trump supporters — to thank for hanging on as long as he did. "Based on judges' votes alone, Spicer should have been eliminated (at least) two weeks ago," Entertainment Weekly notes, "but Karamo Brown and Kate Flannery — both of whom gave far superior performances — were cut instead." Spicer "can't dance, that's literally what it is," Karamo Brown told Bravo's Andy Cohen last week. "But it's also fan vote," and "our president, who should be doing other stuff, has been tweeting 'vote for the man.'" Peter Weber

If you can't thank a veteran today, do the next best thing and donate to a non-veteran!

President Trump's campaign fundraising team didn't miss a beat this Veterans Day, running a Facebook ad on Monday encouraging people to say "THANK YOU, VETERANS" by donating to the president's metaphorical war chest.

Trump, who is not a veteran, famously deferred the Vietnam War draft several times.

The ad, which includes a can't-miss 25 percent off coupon, provoked criticism of the president, with veteran Mark Hertling pointing out the somewhat bizarre timing of the Trump campaign's message. A judge ordered Trump to pay $2 million last week over his alleged mishandling of funds for veterans, which were instead used for political purposes, CBS News reports.

The president also celebrated the day by attending New York City's Veterans Day parade, where he took the time to honor Gold Star families, despite his history of feuding with several of them.

Although if Trump really is burying the hatchet this Veterans Day, he should be sure to get the date right in next year's Facebook ad. Marianne Dodson

It's safe to say the Game of Thrones ending proved a little polarizing for anyone whose favorite character wasn't Bran. (Yes, we see you! All 12 of you!)

But if you were a little let down by the finale of the HBO series, take solace in the wisdom of the Mother of Dragons herself, who says expectations were so high that there's no ending that "would have made everyone happy." Emilia Clarke also says she doesn't plan to act alongside dragons again anytime soon, so temper your expectations for Last Christmas accordingly. Read more at Indiewire. Scott Meslow
