UPDATE: NBC4 reports that Johnson’s wife has also been arrested. Charges on both have not yet been revealed. Not many details as of yet, but TBD is reporting that Prince George’s County Executive Jack Johnson was taken away in handcuffs today and arrested after federal agents executed search warrants at his home and county office. Johnson has reportedly been under investigation by an FBI corruption task force — but the reason why wasn’t immediately clear. Johnson had less than month remaining in his term as county executive — Rushern L. Baker III will take his place in December. Obviously, more on this story as it comes to light.
