President Barack Obama formally endorsed Hillary Clinton in a video released Thursday afternoon.

“I know how hard this job can be. That’s why I know Hillary will be so good at it. In fact, I don’t think there’s ever been someone so qualified to hold this office. I have seen her judgment, I have seen her toughness, I have seen her commitment to our values up close” Obama says in the video, which was tweeted by Clinton’s official Twitter account.

Obama and Clinton will appear together in their first joint campaign trip together next Wednesday in Green Bay, Wisconsin, Clinton’s campaign revealed.

Clinton welcomed Obama’s endorsement in an interview with Bloomberg Politics, saying “it just means so much to have a strong, substantive endorsement from the president. Obviously I value his opinion a great deal personally. It’s just such a treat because over the years of knowing each other, we’ve gone from fierce competitors to true friends.”
