A hotel in small-town Michigan is offering free accommodation to any woman traveling to the state to have an abortion.
The Facebook post has been shared more than 3,000 times.
O'Brien later added an update to the May 16 post, saying she's received telephone numbers of people willing to help drive women to the hotel, which is located about 65 miles north of Detroit.
"We've got some amazing people in our village," she wrote. "We've got your backs."
O'Brien did not immediately respond to ABC News' request for comment Monday morning.
More than 350 pieces of legislation that would restrict abortion access have been introduced in states across the country this year, according to the Guttmacher Institute, a reproductive rights research group that was initially started as part of Planned Parenthood, but officially separated in 2007 and has been operating independently ever since.
So far in 2019, 17 bans on abortion have been signed in 10 states -- but none have gone into effect because they are all facing a legal challenge or have delayed starts. For now, abortion remains legal in every state.
Last month, Michigan's Republican-controlled House of Representatives and Senate both voted to ban second-trimester abortion procedures and make it a felony for doctors to perform them, except to save a woman's life.
But Michigan Gov. Gretchen Whitmer, a Democrat, has vowed to veto any legislation that restricts abortion access.
