The junior senator’s recent decisions surrounding health care have prompted House Rep. Ruben Gallego to accuse McSally of looking out for corporations over people.

One of the Affordable Care Act’s most vocal critics is now refusing to weigh in on the healthcare law’s potential repeal by the U.S. Supreme Court.

This week, the Supreme Court agreed to hear a case that could result in overturning the Affordable Care Act. When asked by The Hill about her stance on the case, Sen. Martha McSally derided the country’s healthcare law, but stopped short of supporting a repeal by the courts.

“ObamaCare is not working,” McSally said, but told reporters that she would not weigh in on a “judicial proceeding.”

McSally’s comment on the Supreme Court case comes days after she revealed her plan to lower prescription drug costs. However, the proposal stops short of other cost-cutting measures approved by the House of Representatives, and was called “a bill for political cover that strengthens those corporations’ power over Arizonans,” Rep. Ruben Gallego, D-Phoenix, said in a statement to the Associated Press.
