New York Democratic Rep. Alexandria Ocasio-Cortez is promoting a primary opponent against a Texas Democrat as she asks voters to remove the last pro-life Democrat in the House.

Ocasio-Cortez took to Twitter on Tuesday to encourage people to support Texas Democratic hopeful Jessica Cisneros in an upcoming runoff election against Democratic Rep. Henry Cuellar for the state’s 28th District.

The congresswoman said “his challenger has a real shot, but needs help.”

Cuellar garnered just 48% of his district’s primary vote in March, forcing a runoff election against Cisneros on May 24.

“Today, we proved just how powerful our movement is and are ready to keep fighting for the future we deserve,” Cisneros said in a statement following the primary. “Together, we will take control back from Big Oil, private prisons, and Wall Street, and put it back where it belongs: with the people.”

Cisneros has repeatedly emphasized her support of “reproductive health care” in her battle against Cuellar.
