Trey Gowdy: We'll subpoena Susan Rice if we have to

South Carolina Rep. Trey Gowdy was not accepting of former national security adviser Susan Rice's refusal to testify before Congress about their investigation into the alleged Russian hacking, and said that if he needs to, he'll subpoena Rice, and force her to sit before Gowdy's subcommittee.

Rice refused to testify because the requests from Sen. Lindsay Graham (R-S.C.) did not have bipartisan support.

Appearing on "America's Newsroom" on Fox News, Gowdy told host Bill Hemmer that they'll take a more forceful approach with Rice, as she is a "very important witness."

“There are other ways to invite people other than via a letter,”  Gowdy said. “There are things called subpoenas. You shouldn’t have to use them with a former national security adviser, but if you do, you do.”

Gowdy speculated that Rice's refusal to testify may be that the information she has is sensitive, but says this is why he's having these meetings behind closed doors.

“Members of Congress don’t pick the witnesses, lawyers don’t pick witnesses. Facts pick the witnesses,” he concluded.
