U.S. Rep. Ken Buck (R-CO) said on a Denver radio show Friday that it was “premature” for the Trump Administration to appoint a special counsel to investigate Russian interference in the last election–and that it’s “just very difficult” at his town halls to get his positive message out “about the good things that are going on” in Washington.

Asked by KDMT 690-AM host Jimmy Sengenberger if he thought it was a “smart move” for the deputy attorney general to appoint Robert Mueller as special counsel, Buck said:

“I think that it was premature,” Buck answered. “I don’t think it was warranted at this time. I can see politically whey they want to remove themselves, the Department of Justice, from this inquiry. And I understand politically why it was done. But as a prosecutor, you wait until you have probable cause before you start doing things like special prosecutions or grand jury or other criminal investigations. So I just felt it was premature.”

Buck is a former Weld County District Attorney.

Buck’s comments came on the day it was revealed that Trump told Russian officials that former FBI Director James Comey was a “nut job” and his firing by Trump alleviated pressure on Trump about his campaign’s Russian ties.

Earlier in the week, a recording emerged of former GOP House Majority leader, Kevin McCarthy, saying he thinks Russian leader Vladimir Putin paid Trump. McCarthy said he was joking, even though he said, “Swear to God” after he made the comment in the audio tape. Multiple Trump officials, including Trump’s Attorney General, Jeff Sessions, have admitted talking to Russians during the campaign.

Buck said Congress and Trump are doing a lot of good work, but “when I go to town halls, trying to the get positive message out about the good things that are going on is just very difficult.”

Asked why, Buck said the media “is fundamentally unfair in this situation; it’s a left-leaning media,” and Trump has “not done us any favors.”

He added that “the left if very well organized and focused on a singular message.”

“I tell ya, Jimmy, I think there are great things happening in the country, and the stock market today is reflecting some of those great things,” Buck said on air. “We have consumer confidence that is outstanding right now. We have low unemployment. You know, I was driving to the airport the other day, from Greeley down to DIA, and I saw five different HELP WANTED signs, and I haven’t see that in years….”

“For some reason, this narrative continues that there’s some sort of collusion between the Trump Campaign and the Russians, and there’s just no hard evidence that leads to that conclusion,” said Buck.

Buck took over Colorado’s Fourth Congressional District when U.S. Sen. Cory Gardner (R-CO) was elected in 2014. Gardner defeated a Democrat, Betsy Markey, to win the seat in 2010.
