Barney Frank Joining CNBC

Former Rep. Barney Frank (D-MA) is joining CNBC as a contributor.

CNBC’s managing editor Nick Dunn tweeted Friday that the former congressman and prickly liberal firebrand had joined the channel.

Frank, who served as the chairman of the Financial Services Committee when he was in Congress, once stormed off the set of CNBC after a heated exchange with the channel’s Mark Haines. Haines and Frank were discussing limiting executive compensation.

“It seems to be that you’re dealing with a model that no longer works,” Haines said referring to Frank’s proposal for changing executive pay rules. The conversation escalated and after Frank repeatedly tried to interject he ended the interview.
