The Hill reports here that Kerry (D-MA) is joining Arlen Specter (D-PA) in calling for a constitutional amendment in response to Citizens United.  From the Hill:

“Sen. Arlen Specter (D-Pa.) was the first senator to call for a constitutional amendment. But since he stated his position in late January, lawmakers have not publicly said what the amendment would contain.”
