“For the one-thousandth time, we have no intentions of firing Bob Mueller,” Sanders said on Fox News.

But Sanders also questioned the legitimacy of the Russia probe and said Congress should look into allegations of wrongdoing under the Obama administration.

"We’re continuing to work closely and cooperating with him and we look forward to seeing this hoax wrap up very soon," she added.

The White House is seeking to tamp down speculation the president could get rid of Mueller in an attempt to foil the sprawling investigation into Moscow’s ties to the Trump campaign.

At the same time, Trump’s GOP allies are attacking Mueller’s team , a move some in Washington say is intended to undermine the special counsel’s findings.

But others, especially Democrats in Congress, are concerned Republicans are building a case to fire Mueller.

“Any attempt by this president to remove special counsel Mueller from his position, or to pardon key witnesses in an effort to shield them from accountability or shut down the investigation, would be a gross abuse of power and a flagrant violation of executive branch responsibilities and authorities," Warner said in a floor speech.

Sanders called the senator's remarks further evidence that “Democrats have no plan, they have no agenda, they have nothing to talk to other than attacking this president.”

Republicans have ramped up their criticism in recent days on Mueller’s team of investigators, accusing them of political bias.

They have seized on anti-Trump texts allegedly sent by a top FBI agent working on the Russia probe. The agent, Peter Strzok, was reassigned over the summer once the texts were discovered.

“It’s something that certainly that should be looked at,” Sanders said.
