Issa was confronted by a Republican constituent who said he feared President Trump's agenda.

“I voted for Reagan, I voted for both Bushes, and I never voted for Obama,” he explained to Issa. “However, I am afraid of President Donald Trump.”

Issa wouldn't defend Trump, and instead pointed to his own support for Rubio during the 2016 Republican primary as a defense.

“I was out of the district campaigning all over for [Marco] Rubio,” Issa responded. “He was my first choice.”

Issa campaigned for Rubio during the primary, but eventually endorsed Trump after Rubio dropped out following a poor performance in Florida's primary.

The California lawmaker was ridiculed on social media Friday after he climbed on to the roof of a building after attempting to speak with protesters.
