Vermont Senator Bernie Sanders raised eyebrows throughout the nation’s capital Wednesday, thanking DC liberals for transforming “radical” and “extremist ideas” into “mainstream American ideas.”

Sanders was speaking at the ‘We the People’ summit in Washington, DC when he praised those in attendance for helping to advance his liberal message, saying his supporters have brought those “fringe ideas” to the masses.

“Many of the ideas that we talked about were thought to be fringe ideas, radical ideas, extremist ideas,” said the Vermont Senator. “Well, you know what? Because of your efforts, those ideas are mainstream American ideas.”

“I want to thank all of the groups here, because whether you know it or not, you have helped transform this country in so many ways,” he added.
