Chip Somodevilla/Getty Images(WASHINGTON) -- A showdown on Tuesday with a breakaway faction of his own party saw House Speaker Kevin McCarthy removed as leader of the chamber -- a historic development that signals chaos to come on Capitol Hill.
Hard-line Republican Rep. Matt Gaetz of Florida led the charge against McCarthy, a fellow conservative. Gaetz introduced a so-called motion to vacate late Monday after criticizing how McCarthy has handled spending and budget fights since Republicans retook majority control of the chamber and claiming McCarthy can't be trusted.
McCarthy defended his record, including most recently in averting a partial federal government shutdown with Democratic support -- calling himself "the adult in the room." But that view did not persuade eight other members of the GOP who, along with the Democratic minority, voted to remove the speaker for the first time in history.
An interim speaker pro tempore was quickly named but an internal election must be held for a permanent replacement. Until then, one half of Congress, which approves key funding legislation and other bills, has veered into uncharted territory.

Oct 04, 5:09 PM EDT Jeffries wishes McCarthy well after ouster
Democratic leader Hakeem Jeffries released a statement Wednesday wishing McCarthy well after he voted to remove him from speakership, and encouraged Democrats to do the same.
"Since January, Kevin and I have had a respectful, communicative and forward-looking relationship," Jeffries said. "On many occasions, we strongly disagreed with each other. However, we agreed to disagree without being personally disagreeable in order to find common ground whenever possible."
Jeffries commended McCarthy's initiatives on economic competition with China and artificial intelligence, stating that work should continue.
"I wish Speaker McCarthy, his family and dedicated staff Godspeed as he begins the next chapter in his public service and professional journey," Jeffries said.

Oct 04, 4:11 PM EDT Many House Republicans want to do away with motion to vacate
Senate Minority Leader Mitch McConnell urged House Republicans to do away with the motion to vacate, contending it "makes the Speakers' job impossible."
Many Republicans ABC News talked to on the House side agree with him. For some, it's a major factor in who they will support for speaker.
Rep. David Joyce, R-Ohio, said he'll back "the first one who starts talking about the fact we're not going to have a stupid rule anymore that allows one person to take a speaker out. That's ridiculous."
"It absolutely has to change," he added, noting if it doesn't, the GOP could find itself right back in this same position.
Even Colorado Rep. Ken Buck, one of the eight Republicans who voted to oust McCarthy, says he's OK with changing the rule from a one-vote threshold back to a five-vote threshold to vacate.
"I'm fine with a five vote. If you can't get five Republicans to say the speaker should be vacated, then live with it. But I don't think the rules are the problem. I think the credibility of the former speaker was the real problem," he said.

Oct 04, 3:20 PM EDT Biden expresses concern over Ukraine aid
In remarks about the speakership showdown, Biden said there is a "lot of work" to get done as Congress faces a Nov. 17 deadline to come to a funding deal or once again risk a shutdown.
"We cannot and should not again be faced with an 11th-hour decision, brinksmanship that threatens to shut down the government," Biden said.
He also expressed concern on the current state of future aid for Ukraine, admitting he's worried it may not happen.
"It does worry me," he said. "But I know there are a majority of members of the House and Senate in both parties who have said that they support funding Ukraine."
At least one lawmaker vying for speaker has long been opposed to additional Ukraine aid.
"I'm against that," Rep. Jim Jordan told reporters on Wednesday. "What I understand is at some point we're going to have to deal with this appropriation process in the right way and we're going to try to do that in the next -- what are we down to? Forty-one days. The most pressing issue on the mind of Americans is not Ukraine, it is the border situation."

Oct 04, 2:13 PM EDT Read Scalise's letter on running for speaker
Scalise made his case for why he should be the next House speaker in a letter to colleagues on Wednesday.
In it, he called the Republican conference a "family" as he recounted the support he received when he was shot during congressional baseball practice in 2017 and suffered life-threatening injuries.
"God already gave me another chance at life," he wrote. "I believe we were all put here for a purpose. This next chapter won't be easy, but I know what it takes to fight and I am prepared for the battles that lie ahead."
Oct 04, 2:00 PM EDT Biden: 'We need to change the poisonous atmosphere in Washington'
President Joe Biden weighed in for the first time on the ouster of McCarthy, calling on Congress to change the "poisonous atmosphere in Washington" and come together.
"More than anything we need to change the poisonous atmosphere in Washington. You know, we have strong disagreements, but we need to stop seeing each other as enemies. We need to talk to one another, listen to one another, work with one another. And we can do that," Biden urged while delivering remarks on student loans at the White House.
Biden said the GOP will need to "reorganize" and that it might "take some time" to select a new leader.

Oct 04, 1:28 PM EDT Scalise enters speaker's race
House Majority Leader Steve Scalise has officially entered the race to replace McCarthy.
The Louisiana Republican, in a lengthy letter to his colleagues on Wednesday, made a pitch for unity as he touted his work as the No. 2 House Republican.
"You know my leadership style I've displayed as your Majority Leader and Whip," he wrote. "I have a proven track record of bringing together the diverse array of viewpoints within our Conference to build consensus where others thought it impossible."
"Our strength as a Conference comes from our unity, and we have seen when we unite as a Conference, we can deliver wins for the American people," he wrote. "Now we need to take those unified positions and work to extract conservative wins from the Democrat Senate and White House by leveraging upcoming deadlines. While we need to be realistic about what can be achieved, if we stay united, we can preserve leverage for the House to secure tangible wins in our impending policy fights."
Oct 04, 11:48 AM EDT Read Jordan's letter announcing bid: Time for GOP to 'come together'

Oct 04, 11:34 AM EDT McConnell pays tribute to McCarthy
Senate Republican leader Mitch McConnell said he is keenly aware of the thankless work it takes to be a Congressional leader as he praised McCarthy in a floor speech.
“I’ve said before, in reference to my own position, that being the leader of your party in the Senate is much like being the groundskeeper at a cemetery. Everybody’s under you, but no one’s listening," McConnell said, adding: “Of course, I doubt that Kevin McCarthy has ever seen himself as above anyone else."
McConnell praised McCarthy's willingness to dive "head first" into worthwhile fights, calling him a trusted and honest partner in leading the GOP caucus.
