Federal investigators: Cabinet secretary and potential Clinton running mate Julian Castro violated Hatch Act

The Washington Post reports:

Housing Secretary Julian Castro violated the federal Hatch Act restricting partisan political activity by federal employees when he praised Democratic presidential candidate Hillary Clinton during an interview conducted from his government office, government investigators found Monday.

Castro is among several potential vice-presidential choices for Clinton, who will formally claim the Democratic presidential nomination next week. The telegenic young Cabinet secretary has been mentioned for months as a prospect to be Clinton’s running mate. He was among the first candidates to go through the formal process of vetting by the campaign.

Mistakes were made.
