The lead Democrat and Republican on the House Oversight Committee meted out a rare bipartisan rebuke of former Trump national security adviser Michael Flynn on Tuesday after seeing private information that confirmed the former administration official failed to disclose foreign income from Russia and Turkey.

The public criticism by the senior Republican on the House’s chief investigative panel is unusual and presents a dilemma for the White House, which was accused of failing to provide everything the committee asked for — an assertion White House press secretary Sean Spicer disputed.

I met Tom Korologos in 1970. I was doing interviews for my dissertation on congressional staffs; he was the top staffer for Wallace Bennett, a veteran Republican senator from Utah. Tom not only granted me an interview but also gave me a ton of time and valuable insights. He knew and loved the Senate, knew and loved politics. He has had a remarkable career in Washington, serving several Republican presidents and also working as a top official with the provisional authority in Baghdad and as ambassador to Belgium. If you asked me to name veteran pols who understand how our government and politics work and should work, he would be high on the list.

That makes my disappointment with him even more painful. Korologos, along with former Ronald Reagan national security adviser Richard V. Allen, wrote an op-ed for The Post last week with advice for their fellow Republicans, headlined “Memo to GOP: Forget 2016. Start thinking 2018 and 2020.” The op-ed conceded the presidential contest to Hillary Clinton — and proceeded to give advice on how to combat the incoming president and regain the party’s mojo.
