Kevin Joseph O’Connell was arrested near his San Rafael home in July on the suspicion that he made threats against the California Democrat in a voice mail that he left at her San Francisco office.
Deputy District Attorney Aicha Mievis announced that O’Connell admitted to charges of criminal threats and threatening a public official, the Marin Independent Journal reported.
Under the terms of the plea deal, the charges were reduced from felonies to misdemeanors. He could have served up to three years in prison under the harsher charges, but he now faces up to a year in prison. O’Connell is expected to be sentenced Nov. 9.
The news comes as the Capitol Police and FBI investigate other threats against Congressional lawmakers.
