WASHINGTON, D.C.: White House hopeful Donald Trump will announce his pick for vice president in New York on Friday (Saturday in Manila), he said on Twitter, as speculation runs rampant over a handful of potential running mates. Among those believed to be at the top of the Republican’s list are Indiana Gov. Mike Pence, New Jersey Gov. Chris Christie and former speaker of the House Newt Gingrich. In an interview Wednesday with Fox News, Trump said he had narrowed the field down to “three, potentially four, but in my own mind, I probably am thinking about two.” The announcement comes just one day after Trump finished campaigning in Indiana alongside Pence, 57, who is seen as someone with a steady tone who might soften Trump’s combativeness.
