DES MOINES (AP) — Iowa first lady Mari Culver has admitted she violated the state’s smoking ban by smoking in a state-owned vehicle.

Gov. Chet Culver signed the ban into law in April, and on Thursday his wife released a statement saying she had quit smoking last year but restarted a few months ago and smoked in a state vehicle.

Mari Culver says she regrets the mistake and promises that it won’t happen again.

The Des Moines Register reported that Culver was seen smoking in a black SUV the state provides to her family. Culver was in the passenger seat with the window rolled down. A state trooper was driving.

Culver declined to comment beyond the statement released by a spokesman, who did not comment about whether she would be fined.
