White House residence staff learned upon arriving for work Friday morning that Angella Reid, the chief usher, had been fired, The Washington Post reports. Citing someone with knowledge of the dismissal, the Post says employees were told Reid had been relieved of her duties. Reid was the first woman and second African-American to serve in the position.

The White House chief usher is the de facto general manager of the building, "handling everything from the large staff ... to fiscal, administrative, and personal duties," the Post writes. Reid assumed the role in 2011 under former President Barack Obama, replacing Stephen Rochon, who was the first African-American chief usher. Chief ushers typically serve for many years; the Post notes there have been only nine people in the position since the beginning of the 20th century.

A White House official confirmed to the Post that the administration had parted ways with Reid. "We are very grateful for her service and wish her the very best," the unnamed official said. Kimberly Alters

After hearing Turkish President Recep Tayyip Erdogan threaten for two years to launch an assault against the Kurds in Syria, President Trump and senior administration officials did not think he would ever go through with it, six people with knowledge of the matter told Axios' Jonathan Swan.

Their discussions started in 2017, with Erdogan telling Trump the Kurds, who hold control of northeastern Syria, are a threat to Turkey and need to be away from the border. Whenever he would say this, Axios reports, Trump would let Erdogan know that if he did invade, he would have to be solely responsible for whatever happened. During one conversation, Trump conveyed that Erdogan shouldn't mess with U.S. troops in Syria, but intimated that they wouldn't be there much longer and would not stay around to help the Kurds, people with knowledge of the matter told Axios.

Usually, Erdogan would take a few steps back, but last Sunday, he told Trump the invasion was on. Trump soon announced that U.S. troops would be pulled back from the border, a move that sparked bipartisan outrage, with lawmakers blasting Trump for turning on the United States' Kurdish allies. Erdogan thought Trump would reel him in, Turkish sources told Swan, and now he is in over his head as he faces international condemnation. Read more at Axios. Catherine Garcia

With her two wins on Sunday, Simone Biles became the most decorated gymnast in world championship history.

Biles took home two gold medals — one for the balance beam and the other for her floor exercise — and now has 25 World Championship medals. Earlier in the competition, she won gold in the team competition, all-around and vault; she came in fifth-place on the uneven bars. The 22-year-old's Sunday wins put her ahead of Vitaly Scherbo, who earned the previous record of 23 world medals during the 1990s.

Biles' floor performance was so outstanding, with a triple-twisting double back, she earned a score of 15.133, one point higher than the second-place finisher, U.S. gymnast Sunisa Lee. Catherine Garcia

President Trump made a grave mistake by pulling back troops in Syria last week, allowing Turkey to launch a military offensive against the Kurds, a retired four-star Marine general told CNN on Sunday.

"There is blood on Trump's hands for abandoning our Kurdish allies," Gen. John Allen said. The Kurdish-led Syrian Democratic Forces worked with the United States for several years to fight the Islamic State, and held control of the northeastern border area. Since the Turkish assault began last week, video footage has emerged purportedly showing Turkish-backed militia fighters shooting Kurdish prisoners. This, Allen said, is a "full-blown ethnic cleansing."

The Kurds oversee prisons holding thousands of ISIS fighters, their families, and supporters, and hundreds escaped during fighting over the weekend. Allen — the former commander of American forces in Afghanistan and former special presidential envoy for the Global Coalition to Counter ISIS during the Obama administration — said this chaos was "completely foreseeable" and "what happens when Trump follows his instincts and because of his alignment with autocrats."

Allen is also unmoved by Trump's approval of $50 million in aid to Syria. This gesture rings "hollow," he said, and there's no way to say if the money will go where it should. "Who's going to administer it and for whom?" Allen said. "Hundreds of thousands are fleeing and the relief agencies are on the move." Catherine Garcia

President Trump's decision to move U.S. troops from northern Syria, paving the way for Turkey to launch an assault against the Kurds, prompted the Kurds on Sunday to reach a protection deal with the Syrian government.

Under this agreement, Syrian government troops will be able to enter Kurdish-controlled northeastern Syria for the first time in years, The New York Times reports. The United States and the Syrian Democratic Forces, a Kurdish-led militia, spent the last several years as allies, fighting against the Islamic State.

There are still ISIS sleeper cells in Syria, and many fear that the Turkish invasion could lead to the terror group's resurgence. Thousands of suspected ISIS supporters are being held in prisons guarded by Kurds, and hundreds escaped during fighting on Saturday and Sunday. Two U.S. officials told the Times the military recently tried to transfer five dozen "high value" ISIS detainees, but feeling betrayed, the Kurds said no.

The Syrian government, which counts Iran and Russia as its allies, said on Sunday it will fight the "Turkish aggression," while Turkish President Recep Tayyip Erdogan said his troops have control over about 70 square miles of territory in northern Syria. U.S. Defense Secretary Mark Esper on Sunday morning announced all American troops will withdraw from northern Syria, in order to stay out of the crossfire. Catherine Garcia

It looks like Sen. Bernie Sanders (I-Vt.) is beginning to distance himself from his good friend Sen. Elizabeth Warren (D-Mass.) policy-wise.

The two Democratic presidential candidates have always gotten along well and are generally ideological allies, especially relative to many of their primary competitors. But Sanders was pretty clear in an interview that aired on ABC's This Week Sunday that Warren has a ways to go before she's at the same point on the political spectrum.

Sanders praised Warren's tenure as a senator and reaffirmed their friendship, but he said "there are differences" in their platforms, namely the fact that Warren has maintained she is a capitalist "through her bones." He said the country doesn't need more regulation, but rather a "political revolution" and he believes he's the only candidate who will stand up to the corporate elite in the U.S. and say "enough." He said that Warren would speak for herself on the matter, but, for the moment, Sanders, who considers himself a democratic socialist, thinks her adherence to capitalism is reason enough to separate them.

The initial analysis of Sanders' comments seems to be that Sanders recognizes he's falling behind Warren in the race, and understands focusing on where they differ might be his best chance at getting back in contention. Tim O'Donnell

Sen. Ted Cruz (R-Texas) had some mixed reviews for the Trump administration Sunday.

During an appearance on CBS' Face the Nation, Cruz told host Margaret Brennan that he believes it was inappropriate for President Trump to have asked the Chinese government to investigate former Vice President Joe Biden and his son, Hunter. Cruz said "elections in the United States should be decided by Americans and it's not the business of foreign countries to be interfering in our elections."

He did, however, praise the administration for agreeing to release the transcript of Trump's phone call with Ukrainian President Volodymyr Zelensky, in which Trump is accused of pressuring his Ukrainian counterpart to investigate the Bidens. And the senator wasn't ready to let the Bidens off the hook, either, saying that if there's "credible evidence" of wrongdoing, he would support a Justice Department probe. He also had some advice for Biden — Cruz urged him to follow in Trump's footsteps and release the transcript of his own conversations with Ukraine from when he was vice president, so that the American people can judge for themselves.
