Former House Speaker Newt Gingrich, also under consideration, had no comment when asked about the latest developments by many media outlets.
A Republican official in touch with Pence's associates said Thursday morning that Pence told those associates he was convinced he was going to be the pick after his Wednesday meeting with Trump. Trump said following Pence's introduction.
Republican presidential candidate Donald Trump (R) and Indiana Governor Mike Pence (L) wave to the crowd before addressing the crowd during a campaign stop at the Grand Park Events Center in Westfield, Indiana, July 12, 2016. The Republican National Convention begins Monday in Cleveland.
All three of the finalists have had extensive conversations with Trump and his family in recent days. IN law forbids candidates from seeking two offices at the same time.
But until an offer is made and accepted, nothing is for certain in this very fluid situation.
"Pence's executive experience as governor allows him to step into the presidential role but his lack of an attack dog reputation may not be that much of a deficit given Donald Trump's talents in that area", said Dickerson. Trump isn't scheduled to announce his choice until Friday. But the former Republican governor announced Thursday he won't seek the job, despite saying he had support from "apparent majority of the Republican State Committee" that would select a new candidate for governor. But he does part ways with Trump on some issues; in December of a year ago, Pence criticized his future running mate's call to ban all Muslims from entering the United Sates, tweeting "Calls to ban Muslims from entering the US are offensive and unconstitutional". The news was quickly echoed by the Indianapolis Star and The New York Times, which reported Trump's advisers had notified G.O.P. officials about the impending announcement.
Gingrich told an ABC News correspondent earlier that he expected to hear Trump's decision after 1 p.m. EDT (1700 GMT) and would not be surprised if Trump chose Pence.
Trump dined with the Pences last night, a Trump adviser also told CNN.
Christie, a former federal prosecutor, joined Trump on Monday for a speech in Virginia, where the governor touted both himself and the former Atlantic City casino tycoon as defenders of "law and order".
Mr Trump and his new running mate will make their first appearance as a team on Friday in NY.
