A large crowd of abortion rights protestors held signs reading “abortion is a human right” and “protect safe, legal abortion" as attendees loudly cheered on Gillibrand and Cory Booker Cory Anthony BookerBipartisan praise pours in after Ginsburg's death DHS opens probe into allegations at Georgia ICE facility Democratic lawmakers call for an investigation into allegations of medical neglect at Georgia ICE facility MORE (D-N.J.).

Women are being treated as “second class citizens under Trump” and are “being ignored,” Gillibrand said, adding Democrats will flip the Senate and win the White House with the help of abortions rights supporters.

Booker and Gillibrand have made abortion rights a central part of their campaigns in recent days after Alabama’s Republican governor signed an abortion ban with no exemptions for cases of rape or incest. They are among the candidates who support a push to pass a law enshrining abortion rights.

Trump distanced himself from the Alabama bill over the weekend, tweeting that he supports exemptions.

Still, Democrats running for president view the issue as a winning one that could galvanize female voters in 2020.

“We will not stand for this attack on human rights,” Booker said to cheers from protestors.

Booker compared the fight over state abortion bans to the civil rights movement, saying people must ’take to the streets.”

”We see people trying to take us backward, but we must go forward,” Booker said, reiterating a campaign promise to pass federal legislation protection access to abortion.
