Last I heard Bush approved the pill for purchase over the counter in the early 2000s for those over the age of 17 and in 2016 a judge declared the age restriction should be lifted. Not sure where the prescription requirement came in.
It was never over-the-counter in the US. Clinton ordered the FDA to investigate it in the 90s, and it was approved in late 2000 by his FDA, not Bush's. The elder Bush had banned its import in 1989.
You are confusing Plan B, the morning after pill, with the abortion pill.
