Megan Robertson (Indianpolis Metro Police Department)

A GOP operative selected to head the campaign to repeal Indiana's ban on Sunday alcohol sales has resigned after being arrested for a DUI after she drove her car into a Hardee's, the Indianapolis Star is reporting.

Republican campaign operative Megan Robertson was arrested on Christmas Eve after hitting the fast food restaurant.

The 32-year-old woman was charged with operating a vehicle while intoxicated, endangering a person, and operating a vehicle with an alcohol concentration equivalent to 0.15 percent or more.

According to the police report, Robertson's  breathalyzer test showed she had a blood alcohol content of 0.168 percent, more than twice the legal limit of 0.08 percent for driving in Indiana.

Police report Robertson told them that she had been at a bar until 1 a.m. and only had two beers.

Robertson was hired late last year to help run Hoosiers for Sunday Sales; a campaign to repeal Indiana's ban on Sunday alcohol sales at grocery, liquor, convenience and drug stores, financed by a coalition of national grocery chains and business groups including the Indiana Chamber of Commerce.

Robertson said she was "ashamed" of the arrest, and resigned from the campaign immediately after the incident.

"I am incredibly ashamed of my poor judgment in this situation," Robertson said in a statement. "I am very grateful no one was injured, and I am very sorry to those I have let down. This lapse in judgment should not reflect on the causes that I have worked on over the course of my career."

The charges against Robertson are misdemeanors and carry a maximum penalty of a year in prison and a $5,000 fine.
