“It’s not true. It’s not true. Stop parroting Democratic talking points,” McSally said. “Health care is a complex issue. Right now it’s not working. Right now people with pre-existing conditions can’t get access to health care on the health insurance market or the individual insurance market because Obamacare has failed.”

The GOP bill, known as the American Health Care Act, included a provision that prohibited insurance companies from denying coverage for people with pre-existing conditions. However, it also provided states an avenue to waive certain regulations, which could have allowed insurance companies to charge people with pre-existing conditions more for coverage, potentially rendering health care unaffordable.

McSally voted for the GOP bill, and reportedly told her Republican colleagues the day of the vote to get this “f—ing thing” done.

McSally’s Democratic opponent, Rep. Kyrsten Sinema, has made health care central to her campaign. The two lawmakers are competing in an open seat race to replace retiring GOP Sen. Jeff Flake.

Sinema accused McSally in a tweet Wednesday of lying about her record in response to a new McSally television ad where she said she has worked to force insurance companies to protect people with pre-existing conditions.
