In other campaign news, the 2.1 million-strong Services Employees International Union has given an early endorsement to President Obama’s re-election bid. In a video statement, SEIU president Mary Kay Henry offered backing to Obama by invoking the Occupy Wall Street movement.

Mary Kay Henry: “And we agree, all across SEIU, that we need to stand for a 99 percent agenda and re-elect our president, Barack Obama, and that those two steps are on the same path that we’ve been taking in building a new movement for social and economic justice in our country, so that we can make the 2012 election about the agenda for the 99 percent.”
