"The president said that he thought there was 'widespread voter fraud,'" Chaffetz told CNN's "New Day" on Tuesday morning.

"I don't see any evidence of that. We're not doing an investigation of that. Sometimes you do, sometimes you don't."

Chaffetz said that while the Oversight Committee won't conduct a probe into voter fraud, it will look into the president's recent allegations that his campaign was wiretapped by the Obama administration. Trump tweeted accusations Saturday morning that Obama ordered surveillance on Trump Tower, without citing any evidence.

"Well the president is directly asking and calling for that," he said. "I've talked with [House Intelligence Committee Chairman] Devin Nunes — they're leading out on that, and we're going to look into it.

"I've learned long enough that you don't presuppose the outcome. When you look around the corner, sometimes you find something that you didn't expect to find."
