Former Secretary of State and Chairman of the Joint Chiefs of Staff Colin Powell on Sunday endorsed Democratic former U.S. Vice President Joe Biden, becoming the first major Republican to publicly back Donald Trump's rival ahead of November's election.
Powell, who led the U.S. military during the 1991 Gulf War under Republican former President George H.W. Bush and later led the U.S. Department of State under President George W. Bush, said Trump was "ineffective" and has only gotten worse since he took office.
"I cannot in any way support President Trump this year," Powell, who did not vote for Trump in 2016, told CNN in an interview.
Asked if he would vote for Biden, he added: "I will be voting for him."
The New York Times reported over the weekend that former Republican President George W. Bush and 2012 GOP presidential nominee Mitt Romney will also not vote for Donald Trump in 2020 - although they have not publicly said who they plan to vote for.
2008 GOP nominee John McCain's wife, Cindy, is said to be voting for Biden, but the New York Time's noted she is unlikely to make a public endorsement.
