Facebook will tell Congress this week that its current "best estimate is that approximately 126 million people may have been served" at least one story posted by the Kremlin-linked troll farm the Internet Research Agency (IRA) between June 2015 and August 2017, according to copies of the prepared testimony of Facebook General Counsel Colin Stretch obtained by CNNMoney and Axios. Facebook has 213 million monthly active users in the U.S., so that would suggest Russian ads hit more than half of U.S. Facebook users during the 2016 election.

Facebook says those posts were "a tiny fraction of the overall content on Facebook," but as CNN's Dylan Byers points out, it's also a big uptick from Facebook's earlier estimates.

Stretch says the IRA served content directly to 29 million users, but those users shared it, broadening its reach to 126 million. Similarly, an estimated 11.4 million people saw ads purchased by the IRA. Stretch says the Russian ads are "deeply disturbing," and "seemingly intended to amplify societal divisions and pit groups of people against each other." Facebook says it does not know how many of the 126 million people actually saw the Russian content they were served.

Twitter and Google will also testify that the Russian trolls used social media to reach more of the electorate than previously acknowledged. Google will say that it has evidence that Russian operatives uploaded at least 1,108 videos to YouTube with 43 hours of content, and paid at least $4,700 for search and display ads, The Washington Post reports. Twitter will acknowledge that 2,752 accounts controlled by Russian operatives, not just the IRA, and 36,000 Russian bots tweeted 1.4 million election-related tweets, reaching 288 million Twitter users.

Secretary of State Mike Pompeo and National Security Adviser John Bolton are generally aligned when it comes to U.S. foreign policy, but that doesn't mean they get along.

Four sources familiar with their relationship told CNN that their stark personality differences and professional styles have caused a rift between the two, which has also been exacerbated by President Trump's "erratic behavior and lack of foreign policy experience." Pompeo, the State Department, and the National Security Council have all dismissed the claims.

But CNN's sources said that Pompeo is not a fan of Bolton's "calculating methods." Bolton often circumvents Pompeo to interact directly with the president, the CIA, and Congress. For example, during a debate over North Korea, Bolton reportedly left Pompeo off messages he sent to the CIA, which included a list of questions he wanted answered, a source within the intelligence community said. Pompeo, who has led negotiations with North Korea, was reportedly not pleased with being left in the dark. Bolton also reportedly has his deputy, Allison Hooker, call up the CIA ahead of meetings with Trump, allowing him to gather intel and keep that information to himself.

Pompeo is not alone when it comes to disapproving of Bolton's workplace behavior. One of CNN's sources, who describes themselves as Bolton's friend, said the national security adviser is "overreaching" and not running the NSC properly. "There is a real feeling outside of the national security council, across the board, that John has his own agenda and is undercutting the president's policies," another source close to the White House said.

Trump, too, reportedly has some issues with Bolton, though that has less to do with the way Bolton operates and more with how he's perceived. The president apparently gets annoyed by Bolton's public profile, especially when he's giving a speech or tweeting because it takes attention away from him. Read more at CNN. Tim O'Donnell

Much like the Democratic presidential primaries, NASA is collecting a long list of names for 2020.

"Travelers" can have their names sent to Mars during NASA's 2020 space launch. The names will be stenciled in tiny letters on chips attached to a rover that will track any signs of life on Mars, the agency said. Researchers are calling the rover a "robotic scientist" that will collect samples and analyze climate on the red planet.

"As we get ready to launch this historic Mars mission, we want everyone to share in this journey of exploration," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate. "It's an exciting time for NASA, as we embark on this voyage to answer profound questions about our neighboring planet, and even the origins of life itself."

Although no humans will be onboard, space-lovers can earn "frequent flyer" miles for the trip and any other mission they choose to submit a name for. Participants will also receive a souvenir boarding pass for participating in NASA's launch.

The rover is slated to reach Mars in February 2021. Participants can still add their names to NASA's list here. Tatyana Bellamy-Walker

Democrats just scored their second subpoena victory of the week.

On Monday, a U.S. District Court judge denied President Trump's request to block the House Oversight Committee's subpoena of his financial records from his accounting firm. And on Wednesday, another judge did basically the same thing, ruling against Trump's suit to block a House subpoena of his financial record from Deutsche Bank and Capitol One.

Last month, the House Financial Services and Intelligence committees subpoenaed the banks for several years of Trump's financial records. Trump, his businesses, and his family immediately sued the banks to stop them from complying. But on Wedenesday, Judge Edgardo Ramos of the Southern District of New York said the subpoenas were broad, but decided they were "clearly pertinent" to Congress' goals, CNN reports. Ramos added that he expects the banks to comply with the subpoenas shortly.

Deutsche Bank has spent years loaning to Trump and his businesses, and said it "would comply with whatever the court ultimately decided," The New York Times notes. Like they did after Tuesday's ruling, though, Trump's lawyers will likely appeal the Wednesday decision. Kathryn Krawczyk

Washington has become the first state to legalize human composting as an alternative to burial or cremation after Gov. Jay Inslee signed the bill into law on Tuesday.

The law also legalizes alkaline hydrolysis, "a process that breaks down bodies using lye and heat," HuffPost explained. Alkaline hydrolysis is legal in some other states, including California, Idaho, and Maine. Both processes will be legal in Washington starting on May 1, 2020.

These alternative methods have been touted by advocates as being more eco-friendly than traditional burial or cremation. As much as "a metric ton of CO₂" could be saved by choosing the process of human composting instead of traditional methods, says Seattle company Recompose.

After the human composting process is complete — which would take about a month — the deceased's loved ones can take the remains home "to grow a tree or a garden," Recompose's website states.

It's possible that Recompose will be the first of many Washington companies to offer this service, though it's unclear exactly how many Washingtonians will decide to avail themselves of this new opportunity.

Secretary of Housing and Urban Development Ben Carson is desperately trying to explain that stunning "Oreo" gaffe.

Carson while testifying before Congress on Tuesday was asked by Rep. Katie Porter (D-Calif.) about REOs, a real-estate term, but responded, "An Oreo?" Porter proceeded to explain to Carson what an REO is as he appeared to not know what the last letter stood for.

Carson in two interviews on Wednesday discussed this viral moment, first on Fox Business, where he claimed he "was having difficulty hearing" Porter. "Of course, I'm very familiar with foreclosed properties and with REOs, have read extensively about them," he said.

In fact, Carson suggested he knows much more about the topic than the Democratic lawmaker because "I suspect when Katie Porter was an expert in this area, things were very different," saying he invited her to speak with his staff so "she would then be able to understand what's going on."

That doesn't explain why Carson struggled to recall what the 'O' in 'REO' stands for, though. To address that point, Carson said in another interview with The Hill, "We throw around acronyms all the time, particularly in government. And you don't really even think about, 'what do the letters mean?' But you know what the thing is. Of course you know what an REO is."

Carson after the gaffe on Tuesday tried to make light of the mistake by posting a photo of himself with a box of Oreos and sending some to Porter's office. She didn't find that very funny, though, telling MSNBC that Carson should not be in his position and that "we're all losing by not having competent, strong, effective, intelligent leadership at HUD."

Sen. John Kennedy (R-La.) has an unusual — and somewhat graphic — way of telling Democrats to get a move on.

House Democrats have spent months in a will-they, won't-they relationship with impeaching President Trump. So in a floor speech on Wednesday, Kennedy made it revoltingly clear that they should impeach the president now or quit talking about it.

"Again I say this gently and I say this hopefully constructively," Kennedy said on Wednesday before very not gently continuing: "The House leadership needs to urinate or get off the pot." Kennedy then broke down his metaphor into more explicit terms, saying House leaders should either "impeach" Trump "and let us hold a trial — he won't be convicted — or they need to go ahead and hold in contempt every single member of the Trump administration." If the latter happens and the issue goes to the court, either Trump will win, or the House will win and "no American with a brain above a single-celled organism is going to want to run for president," Kennedy finished.

The number of House Democrats — along with one Republican — calling for Trump's impeachment continues to mount. Yet despite reported prodding from her staff and even House Judiciary Chair Jerrold Nadler (D-N.Y.), House Speaker Nancy Pelosi (D-Calif.) won't let it happen.
