On "Shepard Smith Reporting" this afternoon, Chad Pergram said many Republican members of Congress are concerned that the Trump administration is surrounded by so much drama that it's going to be difficult to advance their legislative agenda.

He pointed to comments from Senate Majority Leader Mitch McConnell earlier this week and from House Speaker Paul Ryan today, in which both lawmakers expressed their unease.

"Look at what they're trying to do. They have to move health care through the Senate. They have to do tax reform. ... And then the granddaddy of them all is coming, a must-do bill some time this summer or fall: the debt ceiling," Pergram said from Capitol Hill.

He said Republicans are very concerned that all the controversy surrounding the administration is preventing the party from focusing on these pieces of legislation, particularly the debt ceiling bill.

"That really concerns people up here, as President Trump's political capital among Republicans is starting to dwindle significantly," Pergram said.

He added that many Democrats are already floating impeachment, and he's even spoken to a couple Republican lawmakers who said off-the-record that "President Pence" doesn't sound too bad to them.

"To be fair, we're a long way away from that, but just the fact that the 'I-word' is in play on Capitol Hill, there is some blood in the water," Pergram said. "And that's where it gets very hard ... to get on health care, to do the debt ceiling. That's a big challenge."
