Rep. Nancy Pelosi, D-Calif., said Thursday that she had never heard of Jonathan Gruber, the MIT health economist and key architect of the Affordable Care Act whose public comments on the massive health care law have stirred controversy in recent weeks.

“I don’t know who he is. He didn’t help write our bill. And so, with all due respect to your question, you have a person who wasn’t writing our bill, commenting on what was going on when we were writing the bill who has withdrawn – withdrawn some of the statements that he made,” the House Minority Leader said during a press conference Thursday.
