“I have a lot of confidence in Bob Mueller,” McConnell says in the ad.

McConnell has said he believes Mueller should not be fired but said Tuesday he doesn’t think the Senate needs to pass legislation to protect the special counsel.

The ad also shows Vice President Pence saying “the special counsel has a job to do.”

It urges viewers to call their representatives and demand they protect the Mueller investigation.

Republicans for Rule of Law was founded by conservative commentator Bill Kristol and GOP members who don’t want to see Mueller fired during his Russia investigation.

Kristol tweeted about the ad on Monday night, taking a dig at Trump’s television habits by airing the spot during the Fox News show the president reportedly watches.

“You (and President Trump) can see our first TV ad--defending the Mueller investigation--on Fox and Friends in DC tomorrow morning.”

Reports broke on Tuesday that Trump had tried to fire Mueller in December after inaccurate claims that Mueller subpoenaed Deutsche Bank for Trump’s finances.

The White House said Tuesday that Trump “certainly believes” he has the power to fire Mueller after the FBI raided the office and home of his personal attorney, Michael Cohen.

Trump is reportedly mulling firing Rosenstein over the raid since the deputy attorney general personally signed off on the paperwork approving it.

Republicans and Democrats have united in their support of Mueller and urged the president not to fire Rosenstein.
