MILWAUKEE (CBS 58) -- President Donald Trump's rally is about 21 hours away, but supporters are already lining up.

Some say they've been in line outside the UWM Panther Arena since 4:30 p.m. Monday. They're all hoping to get good seats.

"Being in the same room with the President of the U.S. is awesome for one thing, but to be that close is really neat," said a supporter.

"What else is there to do in January besides sit out in the cold in Wisconsin and come see the President of the United States? Why not?" 

The rally is scheduled to begin at 7 p.m. Tuesday evening.
