Romney defended his stance on abortion on Sunday.
WASHINGTON (CNN) - Former Massachusetts Gov. Mitt Romney called Kansas Sen. Sam Brownback "desperate" and "negative" for justifying automated phone calls to Iowa voters calling Romney pro-life at the start of the Republican debate in Iowa on Sunday morning.
In the calls, Brownback's campaign said that "nothing is further from the truth" than Romney's pro-life position. He criticized Romney's wife, Ann, for contributing to Planned Parenthood and said that until two years ago, he pledged to uphold abortion rights legislation. Brownback defended the ad and called it "truthful," while in response, Romney said "virtually nothing in that ad is true."
"I get tired of people who are holier than thou because they've been pro-life longer than I have," Romney said.
Romney has received criticism for blatantly changing his views on abortion. He defended himself for switching his views from being “effectively pro-choice” to pro-life and said that he is "proud of the fact."
