Jim McCain, the youngest son of the late Senator John McCain and an Army 1st Lt., has announced his endorsement of Kamala Harris for president. In a statement on CNN, he revealed that he has switched his voter registration to Democrat, citing his inability to forgive Donald Trump for past comments about his father. McCain, also a Marine, expressed his belief that Harris and her running mate, Tim Walz, represent a group that will help move the country forward. He also criticized Trump for politicizing a visit to Arlington National Cemetery, calling it a 'violation of a sacred place.' Harris's campaign plane slogan is 'A new way forward.' McCain plans to support Harris in November.
