Roe vs Wade is what the law is right now. And yes, it's pro-choice.
The president doesn't have that power.
In the US, congress creates the laws, the supreme court interprets the laws.
The president has various powers like he can veto laws, and he can suggest laws, but he can't pass laws.
The issue at hand is that the Supreme Court is re-interpreting the law to say that the Roe vs Wade decision doesn't hold. In which case the decision becomes the responsibility of each state.
Some of which already have laws that will take effect, and some of which are poorly written and can cause a woman who simply had a miscarriage be arrested. (it's usually not possible to tell the difference between a miscarriage and an abortion).
