Arizona Rep. David Cook told one Department of Public Safety trooper, "Do you know what you're doing, son?'' and told another trooper, "You'll get yours," during his arrest on suspicion of drunken driving Wednesday night in Mesa, a DPS report says.

When Cook was also notified his driving privileges were suspended, he replied "It's fine, my wife works at the MVD," a Department of Public Safety incident report said, adding that Cook's blood-alcohol content registered nearly twice the legal limit.

Cook, R-Globe, responded to the controversy in a Facebook post Thursday evening. He apologized and said the incident taught him a "valuable lesson" about the risks of drinking on an empty stomach.

"No lunch, no dinner, and some drinks with friends sounds harmless enough, but get behind the wheel and try to drive home and you're taking a chance you just shouldn't take," Cook wrote.

"I apologize to all of you because I hold myself to a higher standard and I've let everyone down, friends and family alike."

Cook also wrote that the troopers who responded to the incident "behaved professionally." He didn't address his reported comments to the troopers.

The lawmaker also stated that he didn't ask for "any sort of special treatment as a result of holding office," contradicting a media report that he threatened to invoke legislative immunity to avoid arrest.

Lawmakers in Arizona, under the state's legislative-immunity rule, generally cannot be arrested while the Legislature is in session. Lawmakers are not in session, but will return next month.

A DPS trooper stopped Cook at 11:20 p.m. Wednesday on Loop 202 near McDowell Road in Mesa, after seeing his Ford pickup truck weaving on the freeway, the report states.

The trooper smelled alcohol when he spoke to Cook, whose eyes were bloodshot, and asked him to step out of his truck, according to the DPS report.

Cook initially claimed he had dropped his cellphone in his vehicle, which caused him to swerve, the report said. But he then refused to step out of the vehicle and said, "Do you know what you're doing, son? You're making a mistake," according to the report.

While the report doesn't reference Cook invoking legislative immunity, it states he handed the trooper his vehicle registration along with a copy of his House of Representatives identification card.

The trooper asked again for Cook's driver's license, and he provided it, the report states.

Cook eventually stepped out of his truck.

Throughout the traffic stop, Cook displayed slurred speech, stumbled several times, did not follow trooper instructions and was disoriented during a field sobriety test, which he initially refused to take, the report states.

At one point during the field sobriety test, the report states, Cook ignored instructions to fix his eyes on the trooper's pen, but rather stared into the trooper's eyes.

After instructing Cook three times to look at the pen, Cook stated that he was hit in the head a few weeks back, which affected his balance, according to the report.

Other troopers responded to the scene during the sobriety test. Cook continued to interrupt, raise his voice and ignore troopers' instructions, the report says.

During a "walk and turn test," Cook made several mistakes. After one mistake, he stopped for several seconds, looked at one of the troopers and saluted him with his right hand before continuing the test, a DPS report states.

Shortly after midnight, the troopers arrested Cook on suspicion of extreme DUI and took him to a DPS station for further processing, the report states. His vehicle was impounded.

When Cook was exiting the trooper vehicle, he told one trooper, "I'm fine, don't worry, you'll get yours."

Cook, a rancher representing a rural Pinal County district, has been a member of the state House since 2017 and chairs the House County Infrastructure Committee and serves on the House Public Safety and Natural Resources, Energy and Water committees.

He was re-elected in November by a wide margin.

A breathalyzer test administered after Cook was brought to a DPS station showed his blood-alcohol content was 0.158 percent, the report states, which is about twice the legal limit, the DPS case report said. Arizona's legal blood-alcohol limit for drivers is 0.08 percent.

After he was taken to a DPS station, Cook was provided a private room for 20 minutes to contact a lawyer, the report states.

Around this time, officials told Cook his driving privileges were suspended. Cook responded, "It's fine, my wife works at the MVD," the report states.

Cook was cited and released to his wife, Diana, around 3:15 a.m. Thursday.

Cook didn't respond to requests for comment Thursday afternoon.

House Speaker Rusty Bowers, R-Mesa, said the House will determine actions against Cook after learning the facts and speaking with the legislator.

"I'm disappointed and saddened by Rep. Cook for failing to meet the standard expected of all Arizonans, much less an elected official," Bowers said.

Arizona House Democratic leadership declined to comment on Cook's arrest Thursday evening.
