A draft opinion suggesting the U.S. Supreme Court was ready to overturn the 1973 Roe v. Wade decision establishing the right to abortion sparked a fresh call among progressive Democrats to scrap the Senate's filibuster rule.

"Congress must pass legislation that codifies Roe v. Wade as the law of the land in this country NOW. And if there aren’t 60 votes in the Senate to do it, and there are not, we must end the filibuster to pass it with 50 votes," Independent Senator Bernie Sanders said on Twitter.

Since the start of President Joe Biden's administration, Democrats have wrestled with repealing or modifying the long-held filibuster rule requiring at least 60 votes in the 100-member chamber to advance most legislation, as a way to get around their razor-thin majorities.
