The publisher of the Pittsburgh Post-Gazette is accused of going on a drunken verbal rampage in its newsroom Saturday night in which witnesses say he threatened to “burn the place down” and “close the whole paper.”

John Robinson Block, the vice chairman of Post-Gazette owner Block Communications Inc., is facing a federal labor complaint over the incident. Employees described Block as “ranting like a madman” as he blasted their union and threatened staff, all while forcibly tugging along his sobbing 12-year-old daughter, according to local news outlet The Incline.
