In 2010, O'Keefe plead guilty to a misdemeanor for breaking into former Louisiana Democratic Sen. Mary Landrieu's office to tamper with her phone.
In 2013, O'Keefe had to pay $100,000 to settle a lawsuit filed by a former employee of the Association of Community Organizations for Reform Now, better known as ACORN, after O'Keefe and fellow activist Hannah Giles allegedly solicited advice from ACORN workers on setting up a brothel and evading taxes.
