„Nine months ago, I voted with my colleagues to give the president of the United States of America the authority to use force and I would vote that way again today. It was the right vote then and would be a correct vote today,“ Biden said in a July 2003 speech at the Brookings Institution.

Of the 20 Democrats still running for president in 2020, only two — Biden and Vermont Sen. Bernie Sanders — were in a position to vote on authorizing President George W. Bush to go to war in Iraq back in 2002.
