In the pre-Roe days, nearly 20 states had some sort of law against abortion advertising or publishing information about abortion. In 1975, the U.S. Supreme Court said these were unconstitutional.
Now First Amendment battles over abortion are back. In some states, authorities hostile to both abortion and free speech cite the overturning of Roe as justification for nouveau censorship schemes. If abortion is illegal in a certain locale, they argue, then promoting it there—even if the acts in question would take place out of state—should be illegal too.
