Former House Speaker Newt Gingrich argued Wednesday that Donald Trump could surprise with women voters in November, saying that he is more "pro-woman" than Hillary Clinton.

During a Facebook Q&A Wednesday afternoon, Gingrich pointed out the pay disparity between male and female executives at the Clinton Foundation, where men earn 38 percent more on average, before telling viewers that Trump is more pro-woman than the former secretary of state. He also noted that this likely would come as a "shock" to many voters.

"The first thing that we can do this fall to regain real competitiveness in getting women to decide to vote for us is point out to them the hypocrisy and dishonesty of the Clinton position," Gingrich said before pointing out the figure again, which was reported last month by The Daily Caller.

"Do you really want a president who pays men 38 percent more than women?" Gingirch asked. "And it turns out that's not Donald Trump. Donald Trump pays man women executives very, very well, and he's given them a great deal of responsibility and a great deal of authority."

"So ironically, it's going to turn out at a practical, functionaly economic level that Trump is much more pro-woman than is Hillary Clinton," Gingrich added. "I think that will come as a real shock."

The former House speaker has been mentioned as a possible running mate for the presumptive Republican nominee, with Trump telling the Associated Press that he has narrowed his choices down to five or six names. However, Gingrich has pushed back against that possibility, saying in April that Trump would need "psychiatric help" if he picked the former presidential candidate.
