Presumptive Republican presidential nominee Donald Trump has begun formally vetting prospective vice presidential picks.
The New York billionaire is considering former House Speaker Newt Gingrich and New Jersey Gov. Chris Christie, among what he previously described as a short list of possible running mates. Their inclusion was confirmed by people with direct knowledge of the vetting process who spoke on the condition of anonymity because they were not authorized to discuss the situation publicly.
Trump begins the vetting process with less than three weeks before the start of the Republican National Convention, when he said he would publicly unveil his pick.
Gingrich and Christie, who both received vetting paperwork in the last 24 hours, emerged as prominent Trump allies in recent months, even as the presumptive nominee faced deep and sustained skepticism from many GOP leaders. Trump's relationship with other would-be running mates was badly strained in the bruising Republican primary season, leaving him with a small pool of willing and qualified candidates.
