As Trump narrowed in on his choice of Pence, the two men spent time at both Trump’s golf resort in New Jersey in early July and at the Indiana governor’s mansion this week.
In addition to testing the men’s chemistry together, Trump was reportedly impressed with Pence’s calm demeanor, his experience on Capitol Hill and as a governor, and Pence’s potential to assist Trump in governing, should the ticket win in November.
The announcement will be made publicly at an event at Trump Tower at 11 a.m. Friday morning.
In addition to Pence, Trump has considered former speaker of the House Newt Gingrich, New Jersey Gov. Chris Christie and Army Gen. Michael Flynn for the No. 2 spot on his ticket. Some contenders, including Sens. Bob Corker of Tennessee and Joni Ernst of Iowa, took themselves out of the running.
