Thursday was a chaotic day in the Trump administration, and it left Republicans everywhere in a daze.

It all started with Trump saying he would not sign a funding bill passed by the Senate because it does not include the $5 billion he has requested for border wall funding, all but guaranteeing a government shutdown. This stunned Republican lawmakers, CNN reports. When she heard about what Trump said, Sen. Susan Collins (R-Maine) remarked, "Ugh, are you ruining my life?" Sen. Pat Roberts (R-Kan.) observed, "This is not a good situation." Politico reports the chaos literally made Sen. Bob Corker (R-Tenn.) laugh out loud, saying, "You can't make this stuff up!"

The day went from bad to worse, with Defense Secretary James Mattis resigning in protest of Trump's foreign policy impulses. Senate Majority Leader Mitch McConnell (R-Ky.) said in response that he was "distressed." Sen. Marco Rubio (R-Fla.) said that with Mattis gone, "we are headed towards a series of grave policy errors which will endanger our nation, damage our alliances, and empower our adversaries." Ohio Gov. John Kasich (R) tweeted, "This chaos, both foreign and domestic, is putting America in danger and must stop immediately."

There was also a report Thursday that the administration plans to withdraw troops from Afghanistan, which Sen. Lindsey Graham (R-S.C.), normally a Trump ally, said could be "paving the way toward a second 9/11."

Off the record, the Republican reactions have been even less measured. A senior GOP congressman told CNN, "The wheels may be coming off." A former administration official told The Washington Post, "There's going to be an intervention." And The New York Times' Maggie Haberman reported that some conservatives who have worked for Trump or supported him are saying they "regret" doing so and that the administration is "off the rails," per Mediaite. She added that, considering Republican support would be required to impeach Trump, this "could be a critical moment." Brendan Morrow

The anonymous op-ed writer is still very anonymous.

But there might be a lot more linguistic clues to figure out their identity coming soon, along with a whole new look inside the Trump White House. That's because the anonymous senior official who wrote a New York Times op-ed about the silent "resistance" working under President Trump is writing a whole book called A Warning, their publisher said Tuesday.

It's been more than a year since an op-ed by an anonymous Trump senior official appeared in The New York Times, calling Trump's leadership style "impetuous, adversarial, petty, and ineffective" and saying they are among a quiet "resistance" trying to stop Trump from executing the worst decisions. Pretty much every Trump official denied they wrote it, and the author's identity still hasn't been revealed.

Now, that person has written a whole book promising to be an expansion of the "behind-the-scenes portrait of the Trump presidency" they wrote for the Times. The author's literary agent wouldn't comment on whether the person still worked for the White House, but did say they will "donate a substantial amount of any royalties to the White House Correspondents Association and other organizations that fight for a free press that seeks the truth," per the Times.

The U.K. Parliament voted Tuesday to accept Prime Minister Boris Johnson's Brexit deal but reject his quick timetable.

Parliament first granted Johnson the win on his overall deal before saying it wouldn't fully adhere to the agreement in the next three days. That makes it unlikely Britain will pull out of the EU by the Oct. 31 deadline, BBC reports.

Johnson was already forced by law Saturday to ask the EU for an extension on the U.K.'s membership until January 2020. He said Tuesday he'll "pause" progress on his Brexit legislation until he hears back from the EU, but criticized Parliament for plunging the country into "further uncertainty."

Emily Thornberry of the opposition Labour Party meanwhile called the Oct. 31 deadline an "artificial timetable," per The Washington Post. Labour leader Jeremy Corbyn meanwhile called Johnson "the author of his own misfortune," but did say he'd talk to Johnson to agree on a "sensible" timetable for the prime minister's deal to advance.

Amazon forked over $250 million for the television rights to the Lord of the Rings franchise with the hope of launching their own Game of Thrones-sized hit — and it's clear that they're doing everything possible to guarantee a return on their investment. And what better way to do that than to borrow as heavily as possible from Game of Thrones? Joseph Mawle, who played Benjen Stark on Game of Thrones, has been cast as the villain in Amazon's Lord of the Rings series. Rather surprisingly, his character's name is Oren, not Senjen Bark.

A key diplomat says he was told aid to Ukraine was dependent upon the country announcing investigations into the 2016 election and former Vice President Joe Biden, The Washington Post and The New York Times report.

Bill Taylor, the top U.S. diplomat in Ukraine, testified Tuesday before Congress as part of the House of Representatives' impeachment inquiry, which is examining whether Trump abused the power of the presidency to push for investigations that he thought might help him in the 2020 presidential election and withheld aid to the country until such investigations took place. In previously released text messages, Taylor said it was "crazy to withhold security assistance for help with a political campaign."

In his testimony, Taylor told lawmakers he spoke with U.S. Ambassador to the European Union Gordon Sondland, who "told me that President Trump had told him that he wants President [Volodymyr] Zelensky to state publicly that Ukraine will investigate Burisma and alleged Ukrainian interference in the 2016 election," the Post reports. Burisma is the gas company where Biden's son served on the board.

Taylor reportedly went on to testify that Sondland "told me that he now recognized that he had made a mistake by earlier telling the Ukrainian officials to whom he spoke that a White House meeting with President Zelensky was dependent on a public announcement of investigations — in fact, Amb. Sondland said, 'everything' was dependent on such an announcement, including security assistance.'"

"Sighs and gasps" were reportedly heard throughout the room as Taylor delivered his lengthy opening statement, and Rep. Debbie Wasserman Schultz (D-Fla.) told the Post this was "the most damning testimony I've heard," while Rep. Stephen Lynch, (D-Mass.) told ABC News this is a "sea change," and it might "accelerate" the inquiry's timeline. Brendan Morrow

Russia and Turkey agreed to extend their ceasefire in northern Syria in order to "remove" Kurdish fighters from the area.

After a six-hour-long summit on Tuesday, the two countries agreed to form a "buffer zone" between Turkey and Syria, which is allied with Russia. But first, Turkey will give America's Kurdish allies six days to leave the area before it and Russia jointly begin patrolling it, Turkish President Recep Tayyip Erdogan said Tuesday.

Turkey views the Kurds, who are American allies, as a terrorist threat, and began attacking them within hours of President Trump announcing the U.S.'s withdrawal from the area. Trump later bragged that he'd brokered a five-day ceasefire between Turkey and the fighters. That ceasefire would've expired Tuesday, but now, Turkey has said it will not attack the Kurds for another 150 hours as it forces them out of the land they've long fought to hold on to.

Russia and its ally Syria have also said they'll start "removing Kurdish militias from the border region beginning at noon Wednesday," per The Washington Post. The area will then become a neutral zone between Syria and Turkey, expanding upon a narrower strip of Turkey's border that the U.S. and the country had agreed to establish as a buffer.

Lori Loughlin has just been hit with a brand new charge in the college admissions scandal.

The Full House actress and 10 other parents were charged by a grand jury Tuesday for having allegedly "conspired to commit federal program bribery by bribing employees of the University of Southern California (USC) to facilitate their children's admission," ABC News and CNN report.

Loughlin had previously been charged with conspiracy to commit mail fraud and honest services mail fraud after being arrested in March for her role in what the Department of Justice has said is the largest college admissions scandal it has ever prosecuted. Prosecutors say Loughlin paid $500,000 to have her daughters falsely admitted to the University of Southern California as rowing recruits despite not being rowers.

She's one of the two most high-profile parents charged in the scandal, with the other being Felicity Huffman, who pleaded guilty and is currently serving two weeks in prison. Unlike Huffman, Loughlin has pleaded not guilty. When Huffman received her 14-day sentence, CNN legal analyst Elie Honig described this as "very bad news" for Loughlin, since this sentence would likely be the "absolute floor." TMZ reported Tuesday, though, that prosecutors are "open to plea discussions" with Loughlin.

In a statement Tuesday, U.S. Attorney Andrew Lelling said, "Our goal from the beginning has been to hold the defendants fully accountable for corrupting the college admissions process through cheating, bribery and fraud. The superseding indictments will further that effort." Brendan Morrow
