U.S. President Barack Obama has formally endorsed democratic candidate Hillary Clinton for president today, describing himself as eager to get out and campaign for her, days after she gained the delegates needed to secure the party’s White House nomination.

“I don’t think there has ever been someone so qualified to hold this office,” Obama said in a video released by the Clinton campaign. “I know how hard this job can be, and that’s why I know that Hillary will be so good at it. In fact, I don’t think there’s ever been anybody so qualified to hold this office. I’m with her, I’m fired up and I cannot wait to get out there and campaign with Hillary.”

Clinton’s campaign announced today that she and Obama plan to campaign together in Green Bay on Wednesday. It is their first scheduled joint appearance since Obama endorsed Clinton for president. The stop in Green Bay speaks to the importance both of Wisconsin as a state in the general election and winning that area. Both of the state Democratic and Republican parties held their state conventions in Green Bay this past spring.

Obama and Clinton were rivals during the 2008 Democratic primary that Obama won. Clinton went on to serve as Obama’s secretary of state during his first term in office.
