The Colorado House Ethics Committee voted to investigate further two allegations against Republican Representative Ron Weinberg Wednesday morning.

The determination does not necessarily mean an ethics violation occurred, but it lets the committee move forward in its work.

The group unanimously found probable cause for two of the six claims made in a complaint from fellow Republican Representative Brandi Bradley. One alleges that he copied or inappropriately borrowed a master key for the Capitol building. The other comprises two different claims concerning sexually inappropriate comments he allegedly made to fellow legislators on multiple occasions, including during a gathering at the Brown Palace Hotel in downtown Denver.

“There’s a pattern and practice of behavior here that suggests maybe some form of sexual harassment that crosses the line has happened,” Representative Javier Mabrey, a Denver Democrat on the committee, said.

Committee members dismissed other claims involving allegations that Weinberg carried a firearm while drunk, acted aggressively to Bradley and harassed Representative Stephanie Luck during a 2025 committee hearing, primarily due to scant evidence.

“We basically work in a war zone — early mornings, late nights,” Representative Matt Soper said. “To expect members to always be perfect, cool, calm and collected is a standard that goes beyond a reasonable-person standard. It’s one that could never be achieved or expected.”

The committee also dismissed a claim about possible campaign finance missteps, because the Secretary of State’s office is handling a near identical complaint.

Weinberg has seven days to request an evidentiary hearing. In his response to the complaint, he called the allegations “categorically false, misleading, and without merit.”

“The options that are being presented to the committee and myself have never happened before and nobody knows what to do next. Everyone’s working through what happens if I do pursue a hearing or not,” Weinberg told Newsline.

The committee will eventually recommend actions, if any, the House of Representatives should take in response to the alleged ethics breach. That could include a reprimand, censure or removal from the Legislature.

Weinberg was first appointed to the Legislature in 2023 following the death of Hugh McKean. He won a full term in 2024, but doesn’t plan to run for reelection this year.
