Via The Hill:

Oklahoma Gov. Kevin Stitt signed a bill into law Wednesday that bans abortion at conception in his state, the strictest anti-abortion law in the nation.

Stitt signed House Bill 4327, which prohibits physicians from performing abortions at any point in a pregnancy, unless it is necessary to save the pregnant woman’s life.

The new law immediately went into effect after Stitt signed it.

“I promised Oklahomans that as governor I would sign every piece of pro-life legislation that came across my desk and I am proud to keep that promise today,” he said in a statement.
