WASHINGTON (AP) — The White House and the American College of Obstetricians and Gynecologists say a Republican-led proposal to ban abortion nationwide after 15 weeks would endanger the health of women and have severe consequences for physicians. The measure introduced last week by Republican Sen. Lindsey Graham of South Carolina proposes a nationwide ban that would allow rare exceptions. The legislation has almost no chance of becoming law in the Democratic-controlled Congress. GOP leaders didn’t immediately embrace it and Democrats are pointing to the proposal as an alarming signal of where Republicans would try to go if they were to win control of the Congress in November.
