WASHINGTON (Reuters) – A Democratic bill that would legalize abortion throughout the United States was failing to get the 60 votes needed to advance in the U.S. Senate on Wednesday, amid strong Republican opposition. The vote was continuing on the bill that anticipated a U.S. Supreme Court ruling in coming weeks overturning the landmark Roe v. Wade ruling that enshrined the constitutional right to abortion.
