Gingrich, the former House speaker, is among Trump's top choices, along with Indiana Gov. Mike Pence and New Jersey Gov. Chris Christie. The Indianapolis Star has confirmed that Pence will be dropping out of Indiana's gubernatorial race to run with Trump.
Donald Trump spent some time with Indiana Gov. Mike Pence (R) yesterday at the governor's home, but soon after, Fox News' Sean Hannity flew Newt Gingrich to the Hoosier state for a meeting of his own. Trump, the presumptive Republican presidential nominee, hasn't officially announced his decision-he tweeted that he plans to make the announcement on Friday at 11 a.m.-but signs point to Pence as his top choice.
Mr Gingrich said he was expecting to hear from Mr Trump one way or the other some time after 1pm.
Pence is also a fiscal conservative who advocates for budget reform, and he is one of the more outspoken opponents of President Obama's Affordable Care Act.
The businessman reportedly teased the potential of Pence serving as his running mate while addressing IN rally-goers Tuesday, saying "I don't know if he is going to be your governor or vice president".
"I've been looking forward to a showdown between Mike Pence and John Gregg", Errington said.
Trump told national Republican officials that he had settled on Pence, according to the Republican source, who is familiar with the campaign's operations. Trump said following Pence's introduction.
Senior Trump campaign officials in Cleveland ahead of next week's Republican National Convention would not confirm a report in Roll Call that Trump has selected Pence. Trump's communication office has denied that a decision has been made.
Pence adds some political backbone to Trump's presidential bid, which hasn't exactly been the most disciplined campaign.
Pence was also complimented Thursday at the White House, where press secretary Josh Earnest noted the governor had been doing "important work with the administration to expand Medicaid in his state".
Pence also could give a boost to Trump's campaign fundraising efforts as he challenges the well-organized effort of his Democratic rival, Hillary Clinton. He faces a Friday deadline to withdraw from the governor's race.
The Trump campaign did not immediately respond to a request for comment on Ms Ginsburg's statement. Before that, he served as the representative of Indiana's 6th Congressional District from 2000 to 2012.
Gingrich, who has been active on the social media venue, hosted a Facebook Live event with Trump earlier this month.
