Federal officials are investigating Jack Smith, the former special counsel who investigated then-candidate Donald Trump before his reelection to a second term.

An independent watchdog agency responsible for enforcing a law against partisan political activity by federal employees has opened an investigation into Jack Smith, the Justice Department special counsel who brought two criminal cases against then-candidate Donald Trump before his election to the White House last year.

President Trump and his allies have — without offering evidence — accused Smith of violating the Hatch Act, a federal law that bans certain public officials from engaging in political activity.
