Former Vice President Al Gore will visit Chicago on Friday to endorse the mayoral candidate who ran his unsuccessful 2000 presidential campaign — Bill Daley.

Daley, who served as U.S. Commerce secretary under President Bill Clinton and Gore’s administration, is also planning to announce his climate policy plan at their joint Friday afternoon appearance.

Gore went on to become a prominent advocate for climate change policy with the release of his 2006 documentary, “An Inconvenient Truth.” On Thursday, Gore endorsed the Green New Deal pushed by Rep. Alexandria Ocasio Cortez (D-NY), a bold legislation the sets goals for cutting carbon emissions.
