DENVER (AP) — Gino Campana, a developer running for the Republican nomination for the U.S. Senate in Colorado, has been warned by police he faces arrest for obstruction after arguing with them about to be cited for a noise violation during his daughter’s stay. high school graduation party in 2013, according to police records.

Campana ultimately complied with police directives and was cited for unreasonable noise at the party, which saw dozens of teenagers spill out into an upscale neighborhood in the northern Colorado town of Fort Collins. The Campana campaign said the candidate did not recall arguing with police or being warned he could obstruct their investigation. Police documents show he said bartenders he hired checked IDs to prevent underage drinking, but Campana feared some youngsters were still too drunk to go home by car if the party was interrupted.

Campana is one of seven candidates vying for the GOP nomination to challenge Democratic Sen. Michael Bennett in November.

“Yes, Gino complained about the noise,” spokesman Jerrod Dobkin said. “When more than 100 Italian families and friends get together, it gets a bit noisy at times.”

Officer Brandon Barnes arrived at 10:42 p.m. after police received a complaint, heard loud music and spotted strewn trash and people running from the Campana yard to nearby ones, according to his report for the citation. He called for additional officers due to the size of the group, which includes around “80 to 100 minors”.

Barnes wrote that Campana approached him and his partner and simply introduced himself as Gino. After the officers explained why they were there, Barnes wrote, “Gino then said he was Gino Campana and was on the Fort Collins City Council.” Campana also “made the comment he didn’t want to read about it in the paper tomorrow morning,” Barnes wrote.

Officers asked Campana to disperse the party, but wrote that he refused. “He said he didn’t want all these ‘kids’ – and he kept referring to them as kids throughout our contact – randomly getting into vehicles and driving off if they didn’t have not been checked for alcohol,” the report said. “He then quickly added that no one had been given alcohol at his home, but he could not control whether people were given alcohol or came to his house already intoxicated.”

Campana at one point asked the police to bring a “meter” to measure the noise, arguing that the party did not have to be shut down, officer Christopher Wagner wrote. Eventually, the police told Campana that they were citing him for a noise violation and needed his identity. Campana, they wrote, said he was inside the house and refused to get it.

“Campana said you weren’t giving me a ticket and started to turn around and walk away,” Wagner wrote. “I told Campana he was about to be arrested for obstruction and that he had to cooperate.”

Campana got his ID and sent someone to clean the trash cans on the street. Officers in his court found a beer pong table where the “kids” were playing, but Campana said they were using water.
