WASHINGTON (AP) — The Supreme Court has ended constitutional protections for abortion that had been in place nearly 50 years in a decision by its conservative majority to overturn Roe v. Wade. Friday’s outcome is expected to lead to abortion bans in roughly half the states.

The decision, unthinkable just a few years ago, was the culmination of decades of efforts by abortion opponents, made possible by an emboldened right side of the court that has been fortified by three appointees of former President Donald Trump.

The ruling came more than a month after the stunning leak of a draft opinion by Justice Samuel Alito indicating the court was prepared to take this momentous step.

U.S.Senator Pat Toomey (R-Pa.) released the following statement regarding the Supreme Court’s decision on Dobbs v. Jackson Women’s Health Organization:

“The U.S. Supreme Court’s ruling on Dobbs v. Jackson Women’s Health Organization restores the American people’s ability to determine abortion laws through their elected representatives, as the Constitution requires. Precedents that are wrongly decided should be overturned, just as Brown v. Board of Education was right to overturn Plessy v. Ferguson. This ruling is a win for the unborn, the Constitution, and democratic governance.”

It puts the court at odds with a majority of Americans who favored preserving Roe, according to opinion polls.
