JACKSONVILLE, FLORIDA - APRIL 30: The examination room in A Woman's Choice of Jacksonville clinic, which provides abortion care on April 30, 2024, in Jacksonville, Florida. A six-week abortion ban that Florida Gov. Ron DeSantis signed will go into effect on May 1st. Kelly Flynn, President/CEO of A Woman's Choice of Jacksonville, said, “People have been calling us in desperation all week. We're?staying open to see every patient in need. But there are still thousands who we know Florida abortion care providers cannot see before Wednesday. To the north and the west, Alabama has a total ban; Georgia and South Carolina have six-week bans and many more states have bans in place that prevent people from taking control of their own lives. All the patients we can't?see will now have to travel a very long way IF they have the resources to make the trip. I know many cannot. We hoped we would never have to?operate under these oppressive conditions, and we will help as many as we can to get the abortion care they need and deserve." (Photo by Joe Raedle/Getty Images)
