"Fox News Sunday" anchor Chris Wallace thinks President Trump and the White House should be concerned about Michael Cohen's looming testimony on Capitol Hill.

Cohen, Trump's former longtime personal attorney and fixer, will testify publicly before the House Oversight and Reform Committee on Feb. 27, one day before he is scheduled to be interviewed behind closed doors by the House Intelligence Committee.

The hearings will take place while Trump is in Vietnam for his second summit with North Korean leader Kim Jong Un.

On "Fox & Friends" Friday morning, White House Press Secretary Sarah Sanders said Trump does not have "any concerns whatsoever" about Cohen's testimony.

Wallace, however, believes that the president and his team should be concerned.

"Michael Cohen was the president's personal lawyer, he was the self-proclaimed 'fixer,' he was very involved with Donald Trump for years in his private business. Much less so in his campaign and not at all in his presidency, but he obviously knows a lot about how Donald Trump did business," Wallace said.

He explained that Cohen could reveal more potentially embarrassing information about Trump's hush-money payments to women with whom he allegedly had affairs, so Trump "should be worried."

"Having said that ... I find it curious that you would decide to hold a public hearing on Michael Cohen potentially giving damaging information about the president on the very same day that he is conducting high-stakes diplomacy with the leader of North Korea about nuclear weapons," Wallace said.

He said it's odd that the testimony would not be scheduled in the days before or after the Trump-Kim summit.

"It seems to me that he's a perfectly legitimate person to talk to. I just don't think it makes much sense to do it on the very two days that President Trump is conducting a summit."
