Jessica Cisneros , a progressive attorney challenging Rep. Henry Cuellar (D-Texas), on Wednesday called on members of Democratic Party congressional leadership to withdraw their support for Cuellar, the last abortion rights opponent in the House Democratic Caucus.

Cisneros seized on Monday nights revelation that the Supreme Court plans to overturn the Roe v. Wade decision guaranteeing a federal right to abortions as a reason for House Democratic leaders, nearly all of whom are backing Cuellar , to reconsider their endorsement.

At every turn, my Congressman has stood in opposition to the Democratic Party agenda from being anti-union to being anti-choice, Cisneros said in a statement that she repeated in a video posted to social media. With the House majority on the line, he could very much be the deciding vote on the future of our reproductive rights and we cannot afford to take that risk.

I hope Democratic Party leadership wont stand in the way of delivering for South Texans, she added. I am ready to work with them to deliver on the Democratic agenda.

House Speaker Nancy Pelosi (D-Calif.), Majority Leader Steny Hoyer (D-Md.), Majority Whip James Clyburn (D-S.C.), and House Democratic Chairman Hakeem Jeffries (D-N.Y.) have all endorsed Cuellar. Clyburn is even slated to headline a rally for Cuellar in San Antonio on Wednesday.

HuffPost reached out to the offices of Pelosi, Hoyer and Clyburn for their responses to Cisneros request.

As of late Wednesday afternoon, only Hoyers office has provided a response.

House Democrats passed the Womens Health Protection Act in September of last year to codify Roe and protect abortion rights, Margaret Mulkerrin, a spokesperson for Hoyer, said in a statement. The Senate must now pass it and send it to the President to sign.
