Abortion providers in Texas said that 85 to 90 percent of the procedures they previously performed were after the six-week mark. The law, Senate Bill 8, bans most abortions after about six weeks - before many people know they are pregnant - and authorizes citizens to enforce it. Texas lawmakers did so through a unique legal approach. Several other states have tried over the years to limit or ban abortions before fetal viability but have not managed to maneuver past the courts. A new Texas law that the Supreme Court did not block last week has made abortion functionally illegal in the state.
