Sen. Marco Rubio has earned the support of conservative favorite Rep. Trey Gowdy (R-S.C.), who will join the freshman Senator for a three-day trip to Iowa to rally support for his campaign.

“Marco is a rock solid conservative and a strong leader we can trust,” Gowdy said in a statement proved to reporters. “I look forward to campaigning in Iowa with him, and introducing my good friend to voters across the state.”

Gowdy is a celebrity among many conservatives, thanks to his tough prosecutorial grilling of members of the administration officials during congressional hearings and because he has chaired the Benghazi investigative committee that centers on Hillary Clinton.

Gowdy will join Rubio for seven events in Iowa. He will likely officially announce his support at a campaign rally at the Pzazz! Convention and Event Center in Burlington, Iowa on Monday.

Gowdy’s announcement comes just as many grassroots conservative activists in the state have begun to coalesce around Ted Cruz’s campaign. A CBS/YouGov poll of the state earlier this month showed Cruz earning 40 percent, followed by Donald Trump at 31 percent. Rubio fell to third place with 12 percent of the vote.
