Appearing with MSNBC's liberal opinion host Cenk Uygur, Sen. Bernie Sanders (I-VT) said he would support a constitutional amendment that overrule the Supreme Court's controversial "Citizens United" decision that repealed nearly 100 years of campaign finance law.

The decision permits corporations to anonymously give unlimited sums of money to groups not officially connected with presidential campaigns.

The Washington, D.C.-based Committee for Economic Development suggested last year that the ruling could have the effect of turning corporations into miniature political parties, leading to what one of the Center's trustees called the eventual corruption of American democracy.

"We have to pass a constitutional amendment to end [the] Citizens United ruling that brings forth the radical opinion that a Corporation is not a person and a handful of billionaires cannot pollute and take over the political system by spending unlimited sums of money in secret to elect candidates who support their agenda," Sanders told Uygur.
