In an interview with Jonathan Karl on This Week, Mulvaney played defense, walking back Trump’s comments about Fed Chairman Jerome Powell, saying that Trump “now realizes” he “does not have the ability” to fire him. He also downplayed his own past criticism of the president, telling Karl that he and Trump have “joked about” comments Mulvaney made in 2016 when he called Trump “a terrible human being.”

On the Sunday shows, the Democrats’ critiques of Trump were harsh, if a tad run-of-the-mill at this point. Responding to the shutdown, the party’s representatives reiterated that they won’t allow taxpayer dollars to fund a border wall if they can help it. Republican condemnations of Trump’s recent moves were a much noisier and newsier affair.

On NBC’s Meet the Press, Senator Pat Toomey of Pennsylvania echoed the qualms that Mattis expressed in his resignation letter. “The president does not share, I would say, my view that the Pax Americana of the postwar era has been enormously good for America, it’s been good for the people that I represent, it’s been great for all of us,” Toomey told the host, Chuck Todd, emphasizing fundamental differences between Trump and “the vast majority of Republicans and probably Democrats.” Toomey called upon the Senate to take a more robust foreign-policy role in the Trump era.

Ohio Governor John Kasich, who’s long been rumored to challenge Trump in the Republican presidential primary in 2020, called the withdrawal of troopsfrom Syria a “terrible mistake” in an interview on Fox News Sunday. And on CBS’s Face the Nation, the incoming House Republican Conference Chair Liz Cheney supported Trump’s desire for a border wall, but sang a different tuneon Syria and Afghanistan. “I am deeply, deeply concerned and I oppose strongly the president’s decision apparently to withdraw troops from Syria,” she told the host, Margaret Brennan. “The apparent decision that we’re now going to be looking at withdrawing troops from Afghanistan … these two decisions would be disastrous.”

Senator Rand Paul of Kentucky, who appeared on Face the Nation and CNN’s State of the Union, took almost the opposite stance of Cheney, opposing the wall unless its costs are offset and praising the president for getting out of Syria and Afghanistan. He compared Afghanistan to the Vietnam War. “That was the strategy of Vietnam,” Paul said on Face the Nation. “They waited us out and the Taliban are going to wait us out. They know we will eventually leave and leave we must … The president is right, and I think the people agree with him.”

Senator Chris Coons of Delaware, who was interviewed on Face the Nation after Paul, summed up the Democratic response to Trump’s troop announcements: “By abruptly withdrawing from Syria, President Trump is handing a great big Christmas gift to Vladimir Putin and the Ayatollah Khamenei,” he told Brennan. “When there is a foreign-policy decision that's cheered by Vladimir Putin and Rand Paul, that’s a pretty good sign it’s a terrible idea.” Senate Minority Whip Dick Durbin echoed many Democrats, too, when he offered his reaction to the Mattis news. “It breaks my heart that [Mattis] is going to step aside,” the Illinois Democrat said on Meet the Press. “We counted on him to be there to stop this president from his worst impulse.”

Trump, surrounded by a skeleton crew of government staffers, may well have watched the Sunday shows; he’s been known to tune in from time to time. If so, he would have found few on air to defend him. Way back during the presidential campaign, Trump would tell supporters that “no one knows the system better than me, which is why I alone can fix it!” The candidate’s pronouncement was prescient: It’s become clear that if Trump is going to fix anything, he’s going to have to go it alone.
