After the rally Sunday, Zinke said Comey was right to notify Congress.

"I don't think in this case that holding something of this magnitude secret is wise and prudent," Zinke said. "I think it probably reinforced what a lot of America was already thinking. Certainly the decision to review and open up the case again, I would think there is compelling reason to do so."

Ryan, who has represented Wisconsin’s first congressional district for 17 years, encouraged voters to re-elect Zinke. However the speaker did not utter Donald Trump’s name. The closest Ryan came to referencing Trump was suggesting that Republican plans depended on wins in every race.

“We know what we need to do to bring America back on the right track and the only way we can did that is if we vote for Republicans up and down this ticket. There are men and women of courage and conviction who have earned our support. This man is one of them,” Ryan said, gesturing to Montana’s first-term representative.

The event drew an unexpected appearance by Rep. Greg Walden, R-Ore., chairman of the National Republican Congressional Committee, who called Zinke a leader on natural resource and rural economic issues.
