Gov. Mark Dayton vetoed an abortion bill Monday for the second time in two weeks, the Star Tribune reports.

The bill would require a physician to be physically present anytime a woman is prescribed an abortion pill. It would also require the physical presence of a physician when the pill is swallowed.

Proponents argue that requiring a physician’s presence ensures patients’ safety in the event of side-effects. Dayton defended the pills’ prescription via telemedicine, a method used by about 50 women per year. He called the requirement of a physician's presence a burden on doctors and on women who seek to obtain a legal medical procedure.
