Wednesday and Thursday produced a slew of damaging headlines for an administration battling an impeachment push by Democrats and a revolt by Republicans over the president’s handling of foreign affairs.

If all that wasn’t enough, the White House also announced long-anticipated plans to hold the next Group of Seven (G-7) summit at a Trump-branded property in Miami, dismissing criticism that doing so would raise emoluments issues.

The crescendo came Thursday when the White House’s acting chief of staff Mick Mulvaney Mick MulvaneyOn The Money: House panel pulls Powell into partisan battles | New York considers hiking taxes on the rich | Treasury: Trump's payroll tax deferral won't hurt Social Security Blockchain trade group names Mick Mulvaney to board Mick Mulvaney to start hedge fund MORE, in an on-camera press conference to announce the G-7 decision, said the president had held up security aid to Ukraine partly to pressure the country to investigate a conspiracy theory undermining the conclusion that Russia interfered in the 2016 election.

Mulvaney walked back the remarks hours later, blaming the media for the storm. But in one swoop, the chief of staff had given Democrats fodder and undermined weeks of administration talking points that there had been no quid pro quo on Ukraine.

Mulvaney’s remarks came as witness after witness appeared behind closed doors with Schiff and other lawmakers to talk about the administration’s actions in Ukraine, despite a White House letter to Democrats last week that pledged an end to cooperation with the probe.

Many of those testifying have served up more damaging headlines for Trump — including U.S. Ambassador to the European Union Gordon Sondland, a donor to Trump whose testimony, it was thought, might be more helpful to the White House.

Even as it dealt with the impeachment circus, Trump’s advisers were trying to sell skeptical Republicans on a cease-fire deal with Turkey as a win.

This only churned up fresh criticism over the president’s decision to withdraw U.S. troops from northern Syria, which various Republicans and outside observers have criticized as an abandonment of Kurdish allies, a ceding of U.S. power and an act that have given new energy to ISIS.

In a rare rebuke of Trump, Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellDemocratic senator to party: 'A little message discipline wouldn't kill us' House to vote on resolution affirming peaceful transition of power Republican lawyers brush off Trump's election comments MORE (R-Ky.) penned an op-ed in The Washington Post on Friday afternoon labeling the withdrawal of U.S. forces from Syria a “grave strategic mistake.”

“The combination of a U.S. pullback and the escalating Turkish-Kurdish hostilities is creating a strategic nightmare for our country,” McConnell wrote in the op-ed, which did not mention Trump’s name. “Even if the five-day cease-fire announced Thursday holds, events of the past week have set back the United States’ campaign against the Islamic State and other terrorists.”

There is no link between impeachment and the crisis in Syria, but it is hard not to see political connections between the two. And the Syria fight certainly does not make it easier for Republicans to defend Trump on impeachment.

“I don’t think this is as much as Richard Nixon did, but I’m very mindful of the fact that back during Watergate everybody said, ‘Oh it’s a witch hunt to get Nixon,’” Rooney said Friday on CNN. “Turns out, it wasn’t a witch hunt. It was absolutely correct.”

Former Ohio Gov. John Kasich, a frequent Trump critic, said he’d back impeaching Trump on Friday.

“Look, I fought with people on air over, ‘Is there a quid pro quo’ and ‘Does this rise to the level of impeachment.’ I now believe that it does,” Kasich said during an interview on CNN on Friday. “And I say it with great sadness. This is not something I really wanted to do.”

While Republicans in the Senate are highly unlikely to support impeaching the president, some say they may be less willing to defend him as he disregards their opinions on foreign policy.

“I don’t think it directly makes it more likely that he’ll be removed from office. I do think it makes his political standing significantly weaker in the Senate,” said GOP strategist Alex Conant, who served as communications director for Sen.

“He wants Republican senators out there defending him on impeachment, not attacking him over the Kurds.”

The narrative could worsen for the White House in the near future.

Congress is still mulling sanctions legislation against Turkey that would force Trump’s hand even as he boasts about his agreement.

The House committees leading the impeachment inquiry are expected to interview several more administration officials next week, which could produce additional damaging testimony.
