Dana Balter touts her pro-choice views while questioning her Democratic primary foe's in a new TV ad released by her campaign Tuesday.
The ad, which is airing on broadcast stations in the district, accuses Juanita Perez Williams of opposing abortion and highlights her participation in the March for Life in 2016.
The March for Life is a major anti-abortion rally held annually in Washington.
Balter has said she is pro-choice and if elected to Congress she would oppose efforts to defund Planned Parenthood and other reproductive health care services.
"Voters deserve to know that there are clear policy differences between the candidates," Balter, D-Syracuse, said in a statement. "We're all tired of politicians telling us one thing and doing something else. A 'pro-life' activist claiming she's pro-choice is something voters deserve to know about."
Perez Williams' stance on abortion has been an issue in the campaign since The Intercept, an online news outlet, published a story in late April. The article focused on Facebook posts written by Perez Williams that mention her "pro life advocacy" and participation in the March for Life.
The story also notes that she was endorsed by EMILY's List in the 2017 race for Syracuse mayor. EMILY's List supports pro-choice Democratic women in federal, state and local races.
In a recent interview with The Citizen, Perez Williams said she is "100 percent behind a woman's decision to choose."
"Choice for me is imperative, no matter what side of the aisle you are on, because it ensures things are legal, things are safe and things are accessible," she said.
Perez Williams added later, "Dana and I are on the same side of this issue. She knows that. We both believe in choice. We both believe in respecting the privacy of that choice."
She pledged to support a woman's right to choose and will oppose any legislation that aims to restrict that right. She also opposes attempts to defund Planned Parenthood, which is a major provider of women's health care services.
Both candidates have criticized U.S. Rep. John Katko, the incumbent Republican who represents the 24th Congressional District, for voting to defund Planned Parenthood.
Balter and Perez Williams are vying for the Democratic nomination to challenge Katko, R-Camillus, this fall. The primary will be held Tuesday, June 26.
