Winnebago County Supervisor Mike Stensrud, who police say showed up at a Tuesday morning meeting drunk and armed, said he was drinking that day.
"I just blew it," he said during a phone interview on Wednesday.
Stensrud, 63, of Lake Mills, said he went to treatment in January.
He said he hadn't been drinking until Tuesday.
"It was my choice to drink yesterday," he said. "When you screw up, you have to pay the consequences."
The Forest City Police Department charged Stensrud on Tuesday with public intoxication and carrying a firearm while under the influence.
At 10:16 a.m., shortly after the board of supervisors meeting adjourned, an officer was called to the courthouse for a male who was possibly intoxicated.
The officer spoke to Stensrud in the board of supervisors room and detected the odor of an alcoholic beverage coming from him, according to a criminal complaint.
He asked Stensrud to provide a breath sample and he agreed, the complaint states.
The sample determined Stensrud's blood alcohol level was .09, according to the complaint. By law, if a person has a blood alcohol level of .08 or more, that person is legally intoxicated.
The police officer asked Stensrud if a cup with a straw in it was his and he said it was, the complaint states. He then asked Stensrud if he could see inside the cup and the supervisor gave permission. The cup smelled of an alcoholic beverage, according to the complaint.
At approximately 10:50 a.m., Stensrud agreed to give another breath test and the result was .097, the complaint states.
Stensrud was asked if he was armed and he said he was, according to the complaint.
According to the complaint, the police officer said he took a Smith and Wesson MP 9 Shield pistol out of Stensrud's right front pocket.
The Winnebago County Courthouse does not have a building-wide weapons ban, although the Second Judicial District banned guns in courtrooms, jury rooms and other judicial spaces in county courthouses in 2016.
All Winnebago County Board of Supervisors meetings are live-streamed on YouTube and recorded.
The recording from Tuesday's meeting shows Stensrud drinking from a large plastic cup with a straw in it.
The video ended shortly after the meeting adjourned, but before police entered the board of supervisors room.
Stensrud has been ordered to appear in court at 8:30 a.m. on June 24 to answer to the charges, according to court documents.
Stensrud, who had a 10-year career in the NFL from 1979-89 after attending Iowa State University, has said several times in the past that he doesn't plan to run for re-election this year.
