In the United States, there are three branches of government: Legislative, Executive, and Judicial. The Legislative Branch is Congress, and Executive, the President. Every few years, we vote in elections to choose those people. But the Judicial is special: when one of the nine Justices of the Supreme Court retires or passes away, the Senate, part of Congress, chooses their replacement. Then, they’re there for life.
In 2022, the Supreme Court chose to overturn Roe v. Wade, which previously found a right to abortion is protected by the Constitution. Now, do you remember who the Supreme Court is? That’s right, the Judicial! They get chosen for life. So, that decision was not made by Congress or the President. Constitutional rights also require 38 states and a supermajority in Congress to approve, so there is not currently a way to restore this right aside from the Court.
