Colorado Congressman Ken Buck continued to launch head-turning attacks on the Democrats’ impeachment inquiry, telling a Denver talk show host last week that Jerry Nadler, the Chairman of the House Judiciary Committee, “just doesn’t have a grip on how to run a committee.”

“[Nadler] doesn’t understand the rules that the committee runs by, and is constantly having to take breaks and consult with people,” complained Buck, adding that the committee is “much more partisan, much more prone to bickering” than it was under Republican control.

Buck is a member of the House Judiciary Committee, which started conducting impeachment hearings Sept. 17 after a report surfaced from a whistle blower alleging that Trump tried to enlist the president of the Ukraine to dig up dirt on Trump’s political opponents.

The House Intelligence Committee will be the focus impeachment inquiry, per the instructions of House Speaker Nancy Pelosi.

Nadler’s Democratic primary opponent has said Nadler has botched not only the inquiry but his entire role in holding Trump accountable.

Speaking from the back of the Judiciary Committee to KHOW host Ross Kaminsky, Buck said the former Republican chair of the committee, now-retired Rep. Bob Goodlatte of Virginia, ran the committee in a “way that was very fair and evenhanded.”

Goodlatte was a key player in the impeachment hearings against President Bill Clinton, but he was opposed the impeachment of President Barack Obama.

Nadler couldn’t be reached for comment.

Buck sees nothing wrong with Trump’s request the president of the Ukraine investigate the Bidens, calling it “much ado about nothing, frankly.”

“The president is the chief law enforcement officer in the United States,” said Buck on air. “He asked the chief law enforcement officer in a foreign country to cooperate in an investigation that’s going on in this country and talk to the attorney general, who would have undoubtedly referred anybody from Ukraine law enforcement to the appropriate authorities. So, you know, the president had to make a decision on whether this new administration in the Ukraine was a pro-U.S. and anti-corruption administration. And I think that’s what the conversation was about.”
