Donald Trump railed against the federal prosecutions he once faced during a rare presidential visit to the Justice Department.

The president, once the target of federal prosecution, says he wants to combat “weaponization” of the department, even as he uses its powers to punish enemies and reward allies.

President Donald Trump excoriated the Justice Department prosecutors who investigated him and vowed to use it to target his own enemies in a campaign-style speech at the department’s historic Great Hall on Friday.
