Washington (CNN) Senate Majority Leader Mitch McConnell told Fox News on Tuesday he doesn't believe President Donald Trump will fire Robert Mueller, adding he doesn't want legislation on the issue.

"I don't think he should fire Mueller and I don't think he's going to," he said in the interview. "So this is a piece of legislation that isn't necessary in my judgment."

Last week, a bipartisan group of senators introduced legislation that would make it harder for Mueller to be fired for investigating Russian meddling in the 2016 election.

Sens. Lindsey Graham, a South Carolina Republican, Chris Coons, a Delaware Democrat, Thom Tillis, a North Carolina Republican, and Cory Booker, a New Jersey Democrat, introduced the Special Counsel Independence and Integrity Act, which protects Mueller, including ensure that the special counsel can only be fired for "good cause" by a senior Justice Department official.

McConnell said he won't bring the legislation to the Senate floor.
