Sen. Orrin Hatch (R-Utah) on Thursday issued a stern rebuke to supporters who protested the lawmaker's reported ties to the insurance industry this week.

In response to accusations that Hatch's previous Senate campaigns were in part bankrolled by insurance companies -- a relationship some critics said influenced his vote against the Senate Finance Committee's healthcare bill -- the Utah senator shot back that he had the support of "people all over the health care system including doctors, including hospitals, including insurers, including liberal people, conservative people and moderate people."

"Everybody knows how much money you have to raise to run for the Senate," he told MSNBC. "I think the reason people support me are because of the stands I take."

Then, Hatch criticized -- a group he described as a "scurrilous organization"

"It's funded by George Soros. He's about as left wing as you can find in this country," he said. "And they're up to just one thing, and that is to smear good people. And frankly, they're not gonna smear me without getting kicked in the teeth by me."
