President Donald Trump owes Congress and the American people an explanation about his claims that former President Barack Obama wiretapped Trump Tower, Sen. Susan Collins said on Sunday.

Appearing on NBC's "Meet the Press," the Maine Republican stopped short of saying the president should apologize, but said he should turn over any evidence of wiretapping to the House and Senate Intelligence Committees for their investigations into Russian hacking during the 2016 presidential campaign.


"I'd like to first get to the bottom of this before saying what should be done," Collins said. "I don't know the basis for President Trump's assertion. And that's what I wish he would explain to us on the Intelligence Committee and to the American people. And I do believe he owes us that explanation."

FBI Director James Comey and NSA Director Adm. Mike Rogers are set to testify before the House Intelligence Committee on Monday, where they're expected to answer questions on the Russian hacks and Trump's wiretapping claims.
