A staffer for likely GOP presidential candidate Tim Pawlenty's exploratory committee was arrested in Iowa for public intoxication and trespassing early Wednesday.

According to Des Moines's KCCI-TV, Benjamin Foster was found at about 3 a.m. banging at the back door of a family's home in Ankeny, Iowa, a 20-minute drive north of Des Moines.

The Steward family, who lives in the house, said that Foster was drunk and trying to reach a friend's home. He vomited in the backyard, reportedly scaring their 15-year-old daughter.

Police arrested and charged Foster, then took him to county jail. 

Foster will be placed on a two-week unpaid suspension, according to Pawlenty's exploratory committee.

"Governor Pawlenty is extremely disappointed in Ben’s actions and his behavior does not meet the standards he expects of his employees," Pawlenty strategist Eric Woolson said in a statement.

He added that Pawlenty, "expects him to bear the legal consequences for his action."

Foster apologized in a written statement and said he would take responsibility for his actions.

“Last night, I made a very serious mistake. I take full responsibility for my actions," he said. "I want to apologize to all affected by my poor judgment. I especially apologize to the people who were disturbed during the incident and the arresting officers. I give my word that it will never happen again."

Pawlenty was among the first Republican presidential contender to launch an exploratory committee — his was formed in late March.
