Republican Sen. Jeff Flake (Ariz.) has made an enemy out of President Trump, and Trump's wealthy backers are returning fire. Billionaire Robert Mercer, who helped fund Trump's journey to the White House, has now contributed $300,000 to a super PAC backing Kelli Ward, a former Republican senator who is challenging Flake in the Arizona primary, Politico reports.

Flake is one of the most vulnerable Republican senators up for re-election in 2018, and one who has made a name for himself recently by publicly opposing Trump. In addition to refusing to endorse Trump in 2016 (Trump at one point threatened to spend $10 million of his own money to see Flake fall in 2018), Flake wrote in his new book that the president's conduct "would have had conservatives up in arms had it been exhibited by our political opponents."

“We are so grateful to Mr. Mercer for his courageous support for Kelli Ward, a true conservative champion," said Kelli PAC chairman Doug McKee in a statement. "Early investments in a campaign like this are so valuable." Jeva Lange

More than 150 companies, including major tech organizations and online retailers, made arrangements with Facebook to have special access to users' personal data, even as the social media platform assured people that they had control over their data, The New York Times reports.

The Times reviewed more than 270 pages of documents Facebook generated in 2017 to track the partnerships, and spoke with more than 50 former employees of the company and its corporate partners. Under the arrangement, partners were essentially exempt from the usual privacy rules, the Times reports, with Netflix and Spotify granted permission to read users' private messages; Amazon able to obtain the contact information of users through their friends; and Bing, the Microsoft search engine, allowed to "see the names of virtually all Facebook users' friends without consent."

The records show the deals involved the data of hundreds of millions of users every month, with all active in 2017. The first deals were made in 2010. Steve Satterfield, Facebook's director of privacy and public policy, told the Times these partnerships did not violate the privacy of users or run afoul of the Federal Trade Commission's 2011 consent agreement that prohibited Facebook from sharing user data without permission. Read more about the arrangements — and why data privacy experts are skeptical of Facebook's claim that these partnerships were exempt from regulatory requirements — at The New York Times.

Former first lady Michelle Obama had a little fun with Jimmy Fallon for Tuesday's Tonight Show, and they threw in a little light exercise to boot. The elevator surprise idea is pretty simple — people believing they are taking a normal tour of 30 Rockefeller Center stop at a floor, only to get a glimpse of Fallon and then Obama, and then the doors close. Maybe the conversations inside the elevator got awkward and political on the ride down — this is still 2018, after all — but from what we can see, everyone seemed to have fun, there is legitimate elevator music, and you can watch below.

As 2018 winds to a close, "it feels like the whole country is still nursing a hangover from the 2016 presidential election — Trump is still obsessed with Hillary, Mueller is still investigating Trump, and Democrats are about to launch a slew of new investigations into his campaign," Trevor Noah said on Tuesday's Daily Show. "But now, over two years later, we're still about how deep the Russian rabbit hole goes," including the Kremlin's trolls targeting of one particular group. "It turns out, the Russians spent a lot of effort specifically trying to convince black Americans not to vote," Noah said — or to vote for Green Party candidate Jill Stein, same difference.

"Real black American" Dulcé Sloan came out to give her mixed reaction to the news. "Trevor, I feel disgusted, I feel manipulated, and I feel special," she said. "Russia could have gone after anyone — Latinos, Asians, millennials — but they said, We're going after the ones who count: black people. Can you believe that? I mean, some white people actually do think black lives matter." She had some suggestions for Washington. Watch below. Peter Weber

You say border wall, President Trump says "artistically designed steel slats."

On Twitter Tuesday night, Trump declared that he's figured out the real problem Democrats have with funding a wall along the southern border. "The Democrats, are saying loud and clear that they do not want to build a Concrete Wall — but we are not building a Concrete Wall, we are building artistically designed steel slats, so that you can easily see through it .... it will be beautiful and, at the same time, give our Country the security that our citizens deserve. It will go up fast and save us BILLIONS of dollars a month once completed!"

"Build the artistically designed steel slats!" sure doesn't have the same ring to it as "Build the wall!" Catherine Garcia

In a bipartisan vote, the Senate on Tuesday passed the First Step Act, the biggest overhaul of the federal criminal justice system in decades.

The bill passed with a vote of 87-12, and was backed by conservative and liberal groups. Lawmakers spent more than a year negotiating the bill, which creates more rehabilitation programs, eases mandatory minimum sentencing, reduces the three-strike penalty from life in prison to 25 years, and lets some federal inmates earn time credits by taking part in special programs.

Now, the bill moves to the House, where it also has bipartisan support. After the Senate passed the measure, President Trump tweeted that he looks "forward to signing this into law!" Catherine Garcia

Over the course of a decade, the late George H.W. Bush sponsored a boy living in the Philippines who had no idea that the money, letters, and gifts coming to him from the United States were being sent by a former president.

Bush learned about Compassion International, a nonprofit that connects sponsors with children from poor communities, in 2001, the organization's former president, Wess Stafford, told CNN on Tuesday. Bush's security team did some digging, and after vetting Compassion International, they agreed that he could sponsor 7-year-old Timothy. There were some rules, though; he had to use a pseudonym, to protect Timothy from someone who might target him due to his link to Bush.

For 10 years, Bush sent letters — signed "George Walker" — and funds that paid for Timothy's education, activities, and food. Stafford screened Bush's letters, describing them to CNN as being "the most sweet, spirited letters I have read from any sponsor, but he kept giving hints as to who he could be. He was really pushing the envelope." Bush sent photos of his dog, Sadie, and told Timothy that he was invited to the White House for Christmas. Timothy drew pictures for Bush, who in turn sent him sketch pads, colored pencils, and paint, even though gifts were not allowed.

Timothy didn't find out who his sponsor was until he turned 17 and graduated. He was stunned, Stafford said, never having a clue that his pen pal and benefactor was once the president of the United States of America. Catherine Garcia
