Rep. Mikie Sherrill (D-NJ) has continued to slam her Republican gubernatorial opponent, Jack Ciattarelli, on his ties to the opioid industry despite Ciattarelli’s threat to bring a defamation lawsuit against her for her claims.

Sherrill alleged during last week’s New Jersey gubernatorial debate that Ciattarelli profited from the nation’s opioid crisis through his medical publishing company and was responsible for the deaths of thousands of adults and children. Ciattarelli denied Sherrill’s claims and swiftly threatened to sue her for defamation.
