The U.S. Postal Service released the security clearance application of a former CIA officer who is running for Congress as a Democrat to a Republican group, in what is likely an unprecedented move.

America Rising, a PAC that conducts opposition research on Democratic Party members, obtained Abigail Spanberger’s federal security clearance application through a Freedom of Information Act request, BuzzFeed News reported Wednesday. The group then shared it with the Congressional Leadership Fund.
