And in Los Angeles, demonstrators filled a park near City Hall to show their support for abortion rights.

Thousands of protesters converged in cities across the country on Saturday, nearly two weeks after the leak of a Supreme Court draft opinion that would overturn Roe v.

Gathering near the Washington Monument, some wore shirts that read “Bans Off Our Bodies” and “Keep Abortion Safe and Legal.” They vowed to fight to preserve abortion rights, even as some accepted that Roe would most likely be overturned.

O’Leary Carmona said she hoped the events would allow demonstrators to “build power, both civically and electorally.”.

The marches took place after the publication this month of the draft opinion, which showed that the Supreme Court appeared poised to overturn Roe, the landmark 1973 decision that established a constitutional right to abortion.

Democratic senators failed on Wednesday to advance legislation to guarantee abortion rights nationwide in the face of opposition from Republicans and one Democrat, Senator Joe Manchin III of West Virginia.

“Without abortion, I would not be here,” said Ms.

For some, protesting the draft opinion was not just about protecting the right to abortion.

Renee Chanon, 84, said she has been campaigning for women’s rights since the 1970s, when she first began protesting in support of the Equal Rights Amendment

Now, half a century later, she said she was demonstrating against what she called a “horrifying” leaked opinion
