Rep. Adam Kinzinger (R-Ill.) called Sen. Josh Hawley (R-Mo.) "one of the worst human beings" after the senator sent a letter to Secretary of State Antony Blinken calling for the Biden administration to abandon its support for a prospective Ukrainian membership in NATO. "I hate to be so personal, but Hawley is one of the worst human beings, and a self egrandizing con artist," Kinzinger wrote in a post on Twitter. "When Trump goes down I certainly hope this evil will be layed in the open for all to see, and be ashamed of," the congressman added.
