The National Republican Congressional Committee is attacking a Democratic medical executive running for Congress for her involvement with St. Jude Medical, a company that has come under fire for technical vulnerabilities in its pacemakers and defibrillators and for overcharging veterans for the same devices.

"It is an astonishing display of hypocrisy for Angie Craig to run a campaign ad on her company's record on veterans when that same company was forced to pay a multimillion dollar settlement for overcharging our nation's veterans for medical devices," NRCC spokesman Bob Salera said in a blog post Monday.

The company in 2012 paid $3.65 million as part of a settlement with the Department of Justice over the allegation. The settlement resolved allegations by two whistleblowers that the company violated the False Claims Act that it had inflated the cost of replacement pacemakers and defibrillators purchased by the Departments of Defense and Veterans Affairs. Craig, now running for an open congressional seat in Minnesota, ran media relations for the company at the time.

St. Jude came under renewed scrutiny last week when Carson Block, a prominent short seller, issued a memo to investors warning that the company's devices could be fatally hacked. "The nightmare scenario is somebody is able to launch a mass attack and cause these devices that are implanted to malfunction," Block said in an interview with Bloomberg.

The NRCC said the affiliation should be disqualifying for a congressional candidate. "Angie Craig should apologize to Minnesota's veterans community for her company's history of ripping them off by overcharging them for their medical treatment," Salera said.
