The internal government watchdogs were believed to have been dismissed at several major agencies, though the Justice Department’s was not said to have been among them.

The watchdogs say the removals may be invalid for failing to comply with a 2022 law requiring a 30-day notification to Congress before removals.

President Trump has reportedly fired at least a dozen inspectors general, according to the Washington Post and the New York Times. The dismissals appear to violate federal law because the inspectors general are confirmed by the Senate and any dismissals require 30 days notice to Congress.
