U.S. Rep. Trey Gowdy (R-SC) joined "Fox & Friends Weekend" to discuss the upcoming start of Congress' investigation into alleged Russian interference in the 2016 election.

The evidentiary process is set to begin March 20.

Gowdy said it's unusual for the House of Representatives to be involved with this sort of investigation.

"The House is not equipped to investigate allegations of crime, so that's always a challenge. ... Congress does have a role to play in this investigation, but we don't investigate crime because we're not very good at it," said Gowdy, a member of the House Intelligence Committee.

Gowdy said the committee will look at all facets of any alleged Russian tampering, including election interference or influence, the American response and any potential leaks coming out of the intelligence community.

"The leaks are both illegal and deleterious to our national security, so I'm really interested in how this got out," he said.
