Feingold will vote yes today, but will reserve right to filibuster later

Congress has given in to Wall Street's wishes for three decades and usually with bipartisan support, he said. Feingold pointed out that he was one of eight senators in 1999 to vote against Gramm-Leach-Bliley Act, which he said tore down the firewall between Main Street banks and large securities firms and insurance companies as well as voting against the 2008 bailout.

"Congress needs to get it right this time and finally enact tough reforms to prevent Wall Street from driving our economy into the ditch again," he said. "I will not vote to end debate on this bill unless and until it meets that goal."
