Fox News contributor and former congressman Jason Chaffetz said House Democrats' planned investigations of the Trump administration are "fishing expeditions" that are "not productive for the country."

Rep. Elijah Cummings (D-Md), new chairman of the House Committee on Oversight and Reform, said on "60 Minutes" Sunday his committee will "look at anything."

When host Steve Kroft asked if that could include the Department of the Interior or the EPA, Cummings reiterated, "Anything."

"But the fact that we can look at anything is part of the problem. There's so much," Cummings said. "The Congress doesn't meet but so many days in a year.  And all I'm saying is that we've gotta hit the ground, not running, but flying."

On "America's Newsroom" Monday, Chaffetz, who chaired the House Oversight Committee until he left office in June 2017, said he respects Cummings but he's "very concerned" about the direction of the committee. 

"The committee was founded in 1814 to oversee government expenditures. His interpretation is, they should be investigating anything and everything that has to do with Donald Trump," Chaffetz said.

He said there must be evidence of wrongdoing before a probe is launched, otherwise they are just "fishing expeditions."

"That's not productive for the country, that's not where taxpayer dollars should be going. There's no evidence the president has done something wrong. Then you can't pursue an investigation of it," Chaffetz said.

He added that he's amazed to see Democrats' "newfound belief in openness, transparency and honesty," pointing out that they did not support him when he wanted to investigate Benghazi, the IRS scandal or Hillary Clinton's emails.

"But because it's Donald Trump, suddenly they've got a new set of principles that they're wanting to engage in."
