Sen. John McCain (R-Ariz.) announced Friday that he will not vote for the Republican health-care bill, effectively killing the GOP's last chance at passing legislation to repeal and replace ObamaCare before their Sept. 30 deadline. McCain already stunned his colleagues in the Senate earlier this year when he torpedoed another Republican health-care bill with a tie-breaking no vote in July.

Named for sponsors Sen. Lindsey Graham (R-S.C.) and Sen. Bill Cassidy (R-La.), the bill would convert ObamaCare's subsidies and Medicaid payments to block grants to states plus cut Medicaid sharply. "I cannot in good conscience vote for the Graham-Cassidy proposal," McCain said in a statement. "I believe we could do better working together, Republicans and Democrats, and have not yet really tried."

The GOP can only lose three votes, and Sen. Susan Collins (R-Maine) and Sen. Rand Paul (R-Ky.) have also already come out against the bill. Jeva Lange

President Trump's search for a new chief of staff has take on "the feel of a season of The Apprentice, his former NBC reality show," The Washington Post reports. "Candidates for the job are unsure of the status of the president's deliberations and are being kept largely in the dark from the White House." But there is one major different between reality TV and reality, The New York Times adds: In real life, Trump "famously avoids one-on-one interpersonal conflict," and he absolutely hates firing people.

After months of deliberation, Trump had decided he wanted to poach Vice President Mike Pence's chief of staff, Nick Ayers, to replace his own chief of staff, John Kelly. To make room for Ayers, Trump "had been trying for awhile to pull the trigger on firing Mr. Kelly," the Times reports, adding:

Famous for the "You're fired!" catchphrase and also for hating confrontation, Mr. Trump had looked for others to do the work for him last week — even attempting to arrange for Mr. Ayers to fire Mr. Kelly — according to three people familiar with the events. Finally, Mr. Trump persuaded Mr. Pence and Mr. Ayers to join him in hashing things out with Mr. Kelly in the presidential residence on Friday night. But instead of sticking to the plan to let Mr. Kelly leave with dignity, which Mr. Ayers and others in the White House had urged the president to do, Mr. Trump decided to announce it himself on Saturday. [The New York Times]

Ayers turned down Trump's job offer on Sunday, after Trump had been telling people Ayers had accepted the position, the Post reports. Still, the Times adds, "on Monday, according to several people close to the administration, the president was more focused on his success in dispatching Mr. Kelly than on his anger at Mr. Ayers."

The Late Show found a reason for White House Chief of Staff John Kelly to smile, finally.

Yes, "the White House right now is going through yet another big shakeup," Jimmy Kimmel said on Monday's Kimmel Live. President Trump nominated William Barr to be attorney general — "I saw the headline 'Trump Nominates Barr,' I thought he picked Roseanne," Kimmel joked — and Kelly is out in January. "The president's having a hard time finding someone to replace him," Kimmel said. "It's a tough situation: How do you convince a rat to jump on a sinking ship? It's against their nature."

Kimmel revisited some Trump tweets — when he mocked former President Barack Obama for having three chiefs of staff in three years, when he attacked ex-Secretary of State Rex Tillerson as "dumb as a rock," and when he praised him.

But Kimmel dwelled on Trump's early-morning Monday tweet about "No Smocking Gun" despite digging by "Democrats" and ex-FBI Director James Comey. "Typos aside, this is some argument, because Donald Trump is defending himself by reminding us about the hush money he paid to a porn star and a centerfold, which he calls a 'private transaction,'" Kimmel said. "He's clearly panicked right now — I would not want to be a bucket of KFC in Washington tonight. And what about the 'Smocking Gun'? This isn't the first time he's tweeted the word 'smocking.'" For the good of the nation, Kimmel gave Trump a quick lesson about "ck" words versus "ke" words, like "jock" versus "joke."

On The Late Show, Stephen Colbert dug a little deeper into Comey's testimony before House Republicans — the proximate trigger for Trump's "Smocking Gun" tweet — and then dissected the tweet. "Now some say that's a typo," he said, "but today at a fiery briefing, Deputy Press Secretary Bill Farblah defended the president's tweet." And in the fake press conference, "smocking" suddenly made sense. Watch below. Peter Weber

Russian national Maria Butina will plead guilty Wednesday to working as an unregistered Russian agent "to establish unofficial lines of communication with Americans having power and influence over U.S. politics," with help from her American boyfriend, Republican operative Paul Erickson, and under the direction of Kremlin-linked banker Alexander Torshin, according to a draft plea agreement obtained by ABC News. "Butina sought to use those unofficial lines of communication for the benefit of the Russia Federation."

A 30-year-old purported gun-rights activist, Butina has been in jail since her arrest in July. She signed the plea deal on Dec. 8, and according to CNN, she is already cooperating with federal prosecutors in Washington, D.C. According to the plea deal, Butina said she and Erickson (identified as U.S. Person 1) drafted a proposal in March 2015, later sent to Torshin, in which she wrote she'd already "laid the groundwork for an unofficial channel of communication with the next U.S. administration," which she predicted would be Republican.

Butina traveled the U.S. and met with Republican presidential candidates in 2015, and in December of that year, she helped arrange a trip to Moscow for senior NRA leaders and donors, pushing them to meet with senior Russian officials, including Foreign Minister Sergey Lavrov and Dmitry Rogozin, a deputy to Russian President Vladimir Putin. After that trip, according to U.S. prosecutors, Butina sent Torshin a message, translated to read: "We should let them express their gratitude now, we will put pressure on them quietly later."

Erickson, who's also reportedly a target of federal prosecutors in Washington, wrote an acquaintance in October 2016 that he has "been involved in securing a VERY private line of communication between the Kremlin and key [unnamed political party] leaders through, of all conduits, the [unnamed gun-rights organization]." On MSNBC Monday night, Rachel Maddow connected some speculative dots between the NRA, Russia, and the Trump campaign, and she noted Torshin's sudden "retirement." Watch below. Peter Weber

In a 13-minute address to France on Monday evening, an unusually contrite President Emmanuel Macron laid out some new "strong measures" to address the "economic and social emergency" gripping the country, exposed by four weekends of "yellow vest" protests. Macron said his government would pay for a 100 euro monthly raise in the minimum, eliminate taxes on overtime pay in 2019, cut an "unjust" tax on small pensions, and ask profitable companies to give workers a tax-free bonus this month. He also said he would travel France to begin a dialogue with mayors, regional civil leaders, trade unions, and other stakeholders in France's success. He did not pledge to reinstate a special tax on the richest French citizens.

It is unclear if Macron's concessions, following his scrapping of a planned fuel tax, will defuse the yellow vest protests. Protest leaders said they would continue taking to the streets, but some analysts said they expect the movement to fizzle as Christmas approaches. It's also unclear how France will pay for the proposals, estimated to cost $9 billion to $13 billion. As notable as Macron's fiscal proposals, however, was his uncharacteristically soft tone. "I take my share of responsibility" for the anger roiling France, Macron said. "I might have hurt people with my words." Peter Weber

Stephen Colbert began Monday's Late Show by congratulating outgoing White House Chief of Staff on his imminent departure and for "a job, well, done." President Trump, who had a tense relationship with Kelly from the start and promptly broke his promise to let Kelly break the news of his departure, "already had Kelly's replacement picked out," Colbert noted. But his pick Nick Ayers, turned him down, "and it's not just Ayers — nobody seems to want this job."

"So the president is in desperate need of a chief of staff, and he's got no viable candidates, which is why I'd like to take this opportunity to officially throw my hat in the ring," Colbert offered. "Mr. President, I, Stephen Colbert, am your next White House chief of staff." He said he wouldn't be able to control Trump or bring order to the chaotic West Wing, and he will fight with Trump and disagree with his policies, "but I believe in my heart of hearts that this could be fun for me," Colbert said. "I mean, who would pass up the chance to spend 10 minutes on the deck of the Titanic while it's sinking?"

"I think it's fair to say that being Trump's chief of staff did not work out well for John Kelly," Trevor Noah said on The Daily Show. "Because remember, he came into the job known as a respected four-star general, and now he's leaving the job known as the guy who fired Omarosa." In fact, there's a good reason "nobody wants this job," he said. "We all know by now what happens if you work for Trump. At some point you're going to lose your credibility, and then you spend every day being insulted by a 72-year-old 5-year-old. Who would want that? So many Americans don't want this job, Trump might have to let a Mexican do it." Except Michael Kosta volunteered, too. Watch below. Peter Weber

The Trump administration will formally start the process of lifting federal Clean Water Act protections for millions of acres of wetlands and thousands of miles of streams across the U.S., undoing decades of protections against pesticide runoff, industrial waste, and other pollutants. The proposed rules, to be unveiled by the Environmental Protection Agency as soon as Tuesday, are a victory for agricultural and real estate interests but could degrade the drinking water used by tens of millions of Americans and endanger fisheries and the habitats of migratory birds and other species.

President Trump promised during his campaign to roll back the Obama-era Waters of the United States rules, an expansion of federal protections under the the Clean Water Act of 1972, but the new proposals target protections dating back to the George H.W. Bush administration or earlier. The Trump rules, which will be subject to 60 days of public comment, will keep protections for larger bodies of water but remove federal safeguards for wetlands not adjacent to navigable waterways plus most seasonal streams and ponds. The newly vulnerable streams provided drinking water for as many as 1 in 3 Americans, especially in the arid West, according to scientific studies used by the Obama-era EPA.

The Trump EPA calls that data incomplete and will argue that it is tackling an Obama-era federal power grab against rural farmers. Trump's promise to end the Waters of the United States policy was cheered by farmers, real estate developers, golf course owners, and mining and oil firm. Environmental groups call the new proposal a disaster. "It is hard to overstate the impact of this," Blan Holman, managing attorney at the Southern Environmental Law Center, tells the Los Angeles Times. "This would be taking a sledgehammer to the Clean Water Act and rolling things back to a place we haven't been since it was passed. It is a huge threat to water quality across the country, and especially in the West." Peter Weber
