PHILADELPHIA — Progressive activists in Congress have put mounting pressure on President Joe Biden to direct the archivist of the United States to certify and publish the Equal Rights Amendment — which would become the first explicit mention of women in the U.

Biden announced that the Equal Rights Amendment should be considered a ratified addition to the U.S. Constitution.

The remarks were largely a symbolic gesture of support for a century-long campaign to enshrine gender equality in the Constitution. But advocates said they could add heft to a future legal fight.
