Minnesota Gov. Mark Dayton got his chance to publicly endorse longtime friend Hillary Clinton at the Democratic National Convention in Philadelphia on Thursday.

Dayton spoke for more than four minutes about the qualities he saw in Clinton, particularly while serving together in the U. S. Senate.

“Hillary Clinton has dedicated her life to serving the needs of others,” Dayton told the crowd. “Donald Trump, on the other hand…Well, Donald Trump has dedicated his life to serving himself.”
