Legislation protecting special counsel Robert Mueller Robert (Bob) MuellerCNN's Toobin warns McCabe is in 'perilous condition' with emboldened Trump CNN anchor rips Trump over Stone while evoking Clinton-Lynch tarmac meeting The Hill's 12:30 Report: New Hampshire fallout MORE has sparked deep divisions among Republicans on Capitol Hill.

The bills, which limit Trump’s ability to fire Mueller, have pitted GOP leaders against key members of their own caucus.

Protecting the special counsel through legislation has gained slow but growing momentum among Republicans, as Trump has publicly lambasted and reportedly privately mused about firing Mueller, who is investigating potential collusion between Moscow and the Trump campaign.

GOP leadership has tried to quash the proposals. They argue there is no need to bring up the bills because they don’t believe Trump will ultimately fire Mueller despite reports that he’s moved to in the past before ultimately backing down.

“That’s not necessary. There’s no indication that Mueller’s going to be fired. I don’t think the president’s going to do that, and just as a practical matter even if we passed it, why would he sign it,” McConnell told Fox News.

When Fox News’s Neil Cavuto noted that some Republicans “fear” that Trump will ax Mueller, the GOP leader fired back: "I'm the one who decides what we take to the floor, that's my responsibility as the majority leader, and we will not be having this on the floor of the Senate.”

But that’s done little to stop supporters of legislation insulating Mueller from trying to push their respective proposals forward, marking a high-profile disagreement between rank-and-file members, GOP leadership and Trump.

Grassley chided the media for trying to pit him against McConnell or Trump, who would be unlikely to sign such a bill, arguing he was only trying to do his job as Judiciary Committee chairman.

“I don’t care to be put in the middle of anything. I just plan on doing the work that this committee ought to do,” he said.

It would also give Mueller or any other special counsel an expedited review of their firing. If a court ultimately found they weren’t fired for “good cause” they would be reinstated.

The action stemmed in part from a referral from Mueller’s team, and Rosenstein reportedly approved the move.

But Trump downplayed speculation that he would fire Mueller or Rosenstein while at his oceanfront Mar-a-Lago hotel in Florida.

"They've been saying I'm going to get rid of them for the last three months, four months, five months, and they're still here," he told reporters.

Republicans have worked overtime to warn Trump against firing Mueller, a former FBI director who is deeply respected in Washington, or Rosenstein, who appointed the special counsel.

Now, with at least Tillis and Graham expected to vote with Democrats to support the Senate’s legislation next week, it is poised to pass out of the Judiciary Committee.

What, if anything, comes after that for the bill is unclear. Republicans have shown little interest in challenging Trump, who remains popular with the party’s base, months before a midterm election.

“It’s not constitutional in my view to limit the president’s authority,” he added. “I don’t think he will do it, and I think it would be mistake if he did.”

But supporters of the bill say they will try to gather support for the legislation. Any bill would need 60 votes, including the support of at least 11 Republicans, to clear the chamber.

Tillis said his colleagues should “dispense with the drama” and focus on the long-term merits of the bill as they try to get additional co-sponsors.

“It's something that can lie in the Senate chamber. Facts may lead to passage or not,” he said.

He added separately that despite McConnell’s statements “the reality is it’s on us to get the votes to get it passed.”

Winning over GOP votes in the face of McConnell’s opposition could prove to be a herculean task. The GOP leader is widely respected within the caucus and controls what does — or doesn’t — come to the Senate.

Asked about the “McConnell problem,” Coons quipped: “What McConnell problem? McConnell problem?”

“The more the president does things that are unwise and abrupt,” he said, “the more I think that may persuade Majority Leader McConnell of the importance of preventive action.”
