The Court ruled that the previous interpretation of Roe v. Wade was not correct--there was nothing in the Constitution to guarantee abortion was a protected right, and it overturned the ruling.
That action did not suddenly make abortion illegal, it merely returned the decision back to the States.
If it wanted, Congress could pass laws about abortion, either completely keep it with whatever restrictions it decided, or completely ban it with whatever allowances it decided.
Tread carefully.
I think Congress can legally pass laws that protect innocent lives of Americans but that it can’t pass laws that unconstitutionally allow the murder of innocent Americans.
