Mike Huckabee said there is an "interest and fascination" with former FBI Director James Comey's upcoming testimony to Congress, but not among most Americans. 

"I don't think most Americans are that concerned with what James Comey said or heard when he was having a meeting with the president," Huckabee remarked.

The former Arkansas governor stated that it was Comey's responsibility to report at the time any concerns he had about his private meetings with the president.

He also said Comey may have "more to worry about" at the Senate hearing than the president.

Comey is scheduled to appear before the Senate Intelligence Committee on Thursday to answer questions relating to accusations that the Trump campaign colluded with Russian operatives.

Huckabee's daughter, Sarah Huckabee Sanders, stood in for White House Press Secretary Sean Spicer at today's White House press briefing.

Sanders confirmed that President Trump will not invoke his executive privilege to prevent Comey from testifying, and that the White House wants a "thorough investigation of facts." 

Despite the pressure of the Russia investigation, Gov. Huckabee said he feels President Trump is succeeding in keeping many of his campaign promises.

Referencing a line then-candidate Trump used at his rallies, Huckabee said he doesn't think Americans will "get tired of winning."
