Venture capitalist Blake Masters has changed his tune on abortion now that hes won the Republican nomination in Arizonas U.S. Senate race.

The candidate, endorsed by Donald Trump and bankrolled by Peter Thiel , quietly changed a campaign website section about his positions on abortion this week and was caught in the act by NBC News .

On Thursday, morning, Masters website read: I am 100% pro-life, according to screenshots captured by NBC News.

But then, his campaign released a new ad Thursday in which Masters suddenly claimed to support commonsense regulation around abortion.

Look, I support a ban on very late-term and partial-birth abortion, he says in the ad. And most Americans agree with that. That would just put us on par with other civilized nations.

Ironically, he sought to portray his opponent, Sen. Mark Kelly, as having extreme views on abortion, and accused the Democrat of lying about my views on abortion.
