WESTFIELD, Ind. (WDRB) -- Reporters from all over the world were gathered at the Grand Park Events Center in Westfield, Ind., for Donald Trump's Tuesday evening speech.

Many supporters of the presumptive Republican U.S. Presidential nominee were lining up at noon, hoping to get a good seat.

The interest was fueled in part by rumors that Trump may announce Indiana Gov. Mike Pence as his running mate. Some media outlets reported that there's a 95 percent chance that Trump will choose Pence, but no such decision was made Tuesday.

"I often joke, we will be calling Mike Pence," Trump told supporters Tuesday. "I don't know if he will be your governor or your vice president, who the hell knows."

Trump has said he'll name his choice by Friday. That's an important deadline for Pence, because he has until noon on Friday to withdraw his name from the race for Indiana governor.

The rally began more than an hour late, reportedly because Trump was meeting privately with Pence.
