Two Republican lawmakers were jeered for defending the handling of the Russian investigation.
"The FBI has been way too involved in politics, both sides of the aisle," he said, leading the crowd to chant "Do your job!"
Meantime, at a town hall in Midlothian, Virginia Rep. Dave Brat faced boos when he said that he has not seen evidence of Russian collusion from the Trump campaign.
"In this country, you're innocent until there's evidence," he said.
The House of Representatives is on recess this week, with many lawmakers holding town-hall meetings back in their districts.
