Rep. Ken Buck, R-Colo., on Thursday said former President Donald Trump should tell his supporters to "stand down" as his criminal cases proceed through court.

"I think he absolutely needs to tell all Americans to stand down and allow the judicial system to take its course," Buck said in an interview on MSNBC. "We trust judges, we trust juries, we trust appellate courts. This isn't over until it's over."

The lawmaker's warning against violence comes after Trump surrendered to authorities Tuesday in Fulton County, Georgia. He was booked in Fulton County Jail on felony charges brought by District Attorney Fani Willis related to his alleged attempt to overturn the 2020 election results in Georgia. The former president – the first to be indicted in U.S. history – also faces criminal charges in New York and federal charges in Washington, D.C., and the Southern District of Florida. 

Buck, a member of the House Freedom Caucus and former prosecutor, said the fact that Trump was indicted "doesn't mean there's gonna be a conviction."

"It doesn’t mean that everything in those charges are going to come out at trial the way it’s been charged," Buck said, adding that Trump's supporters should refrain from calls to violence as well. 

"I think that setting a very clear message and also having surrogates send a very clear message that violence will not be tolerated is appropriate," Buck said.

Trump was charged with one count of violation of the Georgia RICO Act, three counts of criminal solicitation, six counts of criminal conspiracy, one count of filing false documents and two counts of making false statements in the Georgia case.
