Bernie Sanders tweeted Wednesday that “abortion is a constitutional right” — and slammed Alabama lawmakers for passing a bill that bans abortion even in the case of rape or incest.

“The attack on women’s rights is happening in Alabama, Georgia and across the country, and we must fight it everywhere. I am proud that my state is fighting back—and I encourage all states to do the same to protect a woman’s right to choose,” the Vermont senator and Democratic presidential candidate said in a second tweet.

Vermont lawmakers are seeking to pass a constitutional amendment to protect the right to an abortion in the state.

The Constitution does not mention abortion, but advocates argue that the Fourth Amendment guarantees a “right to privacy,” and that argument was the basis of the 1973 Roe v. Wade decision, which allowed women to choose whether to end a pregnancy.

Many Republicans, particularly evangelical Christians from Southern states, hope that the conservative Supreme Court will overturn Roe, and are passing bills that could end up before the high court.

The Alabama law would make performing an abortion at any stage of pregnancy, with almost no exceptions, a felony.

It’s now in the hands of the governor, who will decide whether to sign it into law.

Even supporters anticipate that, if the legislation is enacted, courts would block it from taking effect as abortion opponents pursue a long-game legal strategy to try to give states control over abortion access.

On Wednesday morning, abortion rights advocates urged Alabama Gov. Kay Ivey to reject the bill and vowed swift legal action if it is enacted.
