EXIT POLL: Almost Half of Sanders Voters in WV Say They'd Vote Trump in General

Donald Trump said that the best way to preserve the sanctity of life is to make sure the Supreme Court is seated with pro-life justices, and by extension, electing him as president.

"I've become pro-life," Trump said tonight on The O'Reilly Factor. "I was, in a meek fashion, pro-choice, but I've become pro-life. And the reason is I've seen...numerous situations that have made me go that way. I will protect it, and the biggest way you can protect is through the Supreme Court."

He added: "Actually, the biggest way you can protect it, I guess, is by electing me president."

Bill O'Reilly asked if that meant that he would appoint a justice who would overturn Roe v. Wade.

"Well, they'll be pro-life," Trump responded. "And we'll see about overturning, but I will appoint judges that will be pro-life."

Trump also weighed in on his upcoming meeting with House Speaker Paul Ryan, raising campaign funds, his Twitter feud with Sen. Elizabeth Warren and his tax plan.
