All eyes are on the Hoosier State as Donald Trump narrows down his choices for his running mate.

Indiana Governor Mike Pence joined presumptive Republican presidential nominee Donald Trump in Westfield, Indiana Tuesday night. He introduced Trump at a rally in front of thousands of supporters. It continues to fuel speculation that the Hoosier governor may be in the running to be Trump's VP.

“My fellow Hoosiers, we are 119 days away from a great victory in the United States of America when Indiana becomes the first state on the board to make Donald Trump the 45th president of the United States of America!” Pence said.

The crowd of thousands cheered Pence on. Some waited hours in the heat to see the Governor and presumptive Republican nominee side by side.

“We’re ready to put a fighter, a builder and a patriot in the Oval Office of the United States of America! We’re ready for Donald Trump to be our next president!" Pence said.

Pence is widely considered a serious contender to be Trump's running mate. And though Trump delivered his signature stump speech Tuesday night, and localized it to the Hoosier State, he wrapped up his rally with a tease.

“We’re gonna turn things around. We’re gonna turn ‘em around fast. We’re not going to lose Carrier Air Conditioning from Indianapolis. You’ll be calling up Mike Pence, I don’t know whether he’s gonna be your governor or your vice president, who the hell knows?!” Trump said.

As speculation continues to mount, Pence has to make an important decision by Friday. Will he stay on the Indiana ballot to run for re-election as governor of the Hoosier State? Or will he withdraw from his re-election campaign to possibly take on the role as Trump’s vice presidential nominee?
