PITTSBURGH (AP) Donald Trump was showing off his knowledge of all things Pennsylvania during a Pittsburgh rally when he asked a baffling question - about Penn State's famed football coach.

''How's Joe Paterno?'' Trump asked supporters Wednesday night. ''Are we gonna bring that back?''

Paterno died in January 2012 just months after being dismissed following a child sex abuse scandal involving his assistant coach.

But the GOP presidential frontrunner wasn't asking about Paterno. He wanted to know about his statue, which was removed from outside the football stadium four years ago.

That's what The Daily Mail's U.S. political editor David Martosko says on his Twitter page. He says a Trump spokesman confirmed that Trump was referring to efforts to ''bring back'' the statue.

During his appearance, Trump boasted ''I know a lot'' about Pennsylvania.
