6:13 P.M. UPDATE:
Donald Trump says on Twitter that he is delaying the announcement of his vice presidential announcement following the deadly truck attack in France.
After a day of speculation about who might join Trump atop the Republican Party's presidential ticket, Trump tweets on Thursday night: "In light of the horrible attack in Nice, France, I have postponed tomorrow's news conference concerning my Vice Presidential announcement."
Trump had been scheduled to unveil his pick at an 11 a.m. news conference at a hotel in midtown Manhattan.
Late Thursday, a truck drive onto the sidewalk and plowed through a crowd of revelers who'd been gathered to watch Bastille Day fireworks in Nice, France. Authorities say dozens of people are dead.
EARLIER:
WASHINGTON — Donald Trump is on the verge of picking his vice presidential running mate, with top contenders told to expect a decision as early as Thursday afternoon.
On Trump's shortlist: Indiana Gov. Mike Pence, New Jersey Gov. Chris Christie and former House Speaker Newt Gingrich, according to people familiar with the candidate's thinking.
Pence quickly exited a speaking event in Indianapolis on Thursday morning without taking questions from reporters. His staff had not released details of any other planned appearances Thursday.
Pence is running for re-election, but Indiana law prevents him from seeking two offices at once. He faces a Friday deadline to withdraw from the governor's race.
A Republican familiar with Pence's thinking said the paperwork has been drawn up for him to take that step. However, the documents have not been filed, according to the Republican, who insisted on anonymity because that person was not authorized to publicly discuss Pence's plans.
Trump was making his final decision from California, where he is scheduled to attend a series of fundraisers at a distance from many of his closest advisers. His campaign chairman, Paul Manafort, is currently in Cleveland, and none of his children are in the state with him.
All three of the finalists have had extensive conversations with Trump and his family in recent days.
