Republican Katie Arrington's suspended security clearance is becoming an issue in her primary campaign against incumbent South Carolina Rep. Nancy Mace. Arrington says Mace is mischaracterizing a dispute that resulted in her departure from a job at the Pentagon. Arrington says her security clearance was suspended in 2021 when officials accused her of an improper disclosure of classified information. Arrington says she did nothing wrong, a contention backed up in an affidavit from the officer who gave her intelligence briefings. The dispute is likely to surface at a debate between the two on Monday. The primary is June 14.
