A liberal dark money group with ties to a super PAC run by allies of Senate Minority Leader Chuck Schumer is going up on television with a new ad again attacking U.S. Sen. Dean Heller over his positions to repeal and replace the Affordable Care Act.

The 30-second spot, which is called “Personal,” says Heller “lied” to Nevadans about their health care, citing his vote on a motion to proceed to debate on the House’s repeal and replace proposal after saying just a little more than a month before that he would vote against the motion. The ad, which begins airing Tuesday, will run statewide and is backed by a $820,000 buy, part of the 501(c)(4) political advocacy group Majority Forward’s ongoing buy.

The Senate Majority PAC, the super PAC run by Schumer’s allies, has described Majority Forward as an “allied organization” with “shared office space, shared staff,” according to the Center for Public Integrity.

“Your health is personal, so take it personally your own senator lied to you about your health care,” the narrator says in the spot.

The ad says that Heller “voted to let insurance companies deny coverage for pre-existing conditions,” “charge older Nevadans more for the same care,” and “raise prescription drug costs” when he supported a motion to proceed to debate over the House’s repeal and replace bill in July 2017 after previously saying he wouldn’t.

“After he lied to you about your health care, how can we trust anything Dean Heller says?” the narrator says.

The House’s repeal and replace bill was was expected to weaken protections for people with pre-existing conditions, allowed insurers to charge those approaching age 65 more for coverage than younger people and allowed states to waive or eliminate requirements for prescription drug coverage. However, the House’s proposal was never under serious consideration in the Senate and was considered the vehicle to open discussions on the Senate’s repeal and replace proposals, not as an end unto itself.
