"The campaign is. If you have any questions or comments it'd probably be better if you directed those towards the campaign," he said. "Just talk to the campaign, they're the ones dealing specifically with this issue. Right now, I'm just worried about jobs and the economy."
Heller supported that push as well, and signed a letter with the rest of the state delegation urging federal officials to keep the center open.
He wouldn't say what he thought of the investigation, but stood by his support of the program.
"Of course — I signed the letter," Heller said.
His campaign argued that the larger issue in the investigation wasn't the medical center they both defended but a letter she wrote to a subcommittee chairman in charge of Medicare funding pushing back against plans to decrease Medicare reimbursement rates for kidney dialysis.
"Not only was her husband one of these doctors, but the same day she received campaign contributions from kidney doctors. The New York Times pointed out that her arm twisting resulted in a $250 million savings for Berkley’s husband’s industry," said Heller spokeswoman Chandler Smith. "This is the kind of behavior that led a panel of five Republicans and five of her own Democrat colleagues to unanimously decide to create an investigative subcommittee on the basis of a non-partisan report for the first time since 2009."
The investigation is highly unlikely to wrap up before the election.
Berkley and Heller are locked in a tight race, which The Hill rates a "tossup."
