Rep. Marsha Blackburn said Monday she has faith that President Donald Trump's attorney Rudy Giuliani will represent him well, including on whether the president could pardon himself, but she doesn't think her constituents care much about the Russia investigation.

"When I'm in Tennessee and I'm talking with people from Tennessee, this kind of hype around the special counsel doesn't create one job or economic opportunity," the Tennessee Republican, who is seeking her party's nomination for the U.S. Senate, told Fox News' "America's Newsroom."

"People are tired of hearing about it."

People are more concerned with talking about tax cuts, jobs, the border, and having constitutional judges, Blackburn added.

"Tennesseans are focused on a few things, what they want their U.S. senator to do, what they want their member of Congress to do," she said.

"The special counsel is out there but it is not a top of mind issue. They do want the federal government to be fair. They want to be able to trust their government, and they see a lot of this as an erosion of that trust."

Blackburn also said she does not know if Trump and special counsel Robert Mueller should participate in an interview, and she had no opinion about who wrote a letter published in The New York Times Saturday, in which the president's attorneys argued in January that Trump could not have obstructed justice because, as the nation's chief executive, he has full authority over all federal investigations."

"I'm sure they're trying to find out," she said about the letter's writer.

Meanwhile, she said she gives Trump and Secretary of State Mike Pompeo a "lot of credit" for getting North Korea to the table, and she thinks this is a "very hopeful time."

"When you read some of the things coming from Japan and South Korea, and indeed that entire Indo-Pacific region, we are hopeful there can be movement to denuclearization, something that is verifiable, something that is irrevocable," said Blackburn.

"I think that would be a very positive step."
