California has joined Connecticut in passing a law to shield abortion providers and patients from lawsuits in other states.

This is a useful partial step, but a woman that wants to travel from Texas to California for an abortion will need transport in Texas to reach California. California laws can't shield a person or company in Texas that provides that transport.

Also, if a state makes it a crime to travel to California (for instance) for an abortion, I don't think California can protect those women from prosecution if they returning home afterwards.

I wonder what the Supreme Court would say about the constitutionality of a law in state A that penalizes people for traveling to state B and doing something which is lawful in state B. A reasonable Supreme Court would say that one state can't impose its own jurisdiction on other states. But with the Supreme Court under the control of religious fanatics, ready to tear up all manner of precedents to get their way, I fear that they will construct some excuse to "bless" such laws.
