The Oklahoma governor is a potential Trump VP candidate

Washington (CNN) Oklahoma Gov. Mary Fallin wouldn't guarantee Saturday that the GOP will change its platform on abortion despite Donald Trump's stated desire to allow for exceptions in cases of rape, incest or to save the life of the mother.

Speaking to CNN's Jake Tapper, Fallin, the co-chair of the party's platform committee, would only say that the party will "remain pro-life."

"I know that Donald Trump has said as a candidate that he believes in life, and I think the majority of the Republican Party does believe in life -- that has been an important part and plank of our platform as a political party," Fallin said.

The Oklahoma governor -- and potential Trump running mate -- said the platform's decisions will be up to the party even though Trump is now the Republican standard-bearer.

"He will have representation -- he's going to be the presumptive Republican nominee -- and certainly he will have a voice with his people, who will make recommendations, too," Fallin said. "But in the end, this platform is driven by grassroots Republican people throughout the nation who will represent the very values and principles of the Republican Party."
