ERA advocates in the U.S. have waged a 100-year fight just to get gender equality enshrined in the Constitution.

“The women of this country are exhausted, so we are leveraging every tool available,” said Rep. Ayanna Pressley (D-Mass.), co-chair of the ERA Caucus.

“We won’t stop until the ERA is officially part of the Constitution,” said fellow co-chair Rep. Cori Bush (D-Mo.). “We owe it to our daughters, to the next generation, to those who fought before us.”
