The U.S. Postal Service apologized Thursday for releasing the security clearance application of former CIA operative and current congressional candidate Abigail Spanberger.

USPS “deeply regrets” handing over employment records for Abigail Spanberger, including the SF-86 clearance application form, to a Republican group that conducts opposition research into members of the Democratic Party. The postal service had retained the records from when she worked there while waiting for the CIA to run a background check on her. She had earlier received a conditional job offer from the spy agency.
