evidence: Jeff Flake, former U.S. senator from Arizona and ambassador to Turkey, announced Sunday he is endorsing Democrat Kamala Harris for president and encouraged other Republicans to "put country over party" and do the same. [...] Another well-known Latter-day Saint politician and anti-Trump nemesis , U.S. Sen. Mitt Romney, R-Utah, also has bucked the GOP standard-bearer, but he has not publicly backed Harris. Flake’s endorsement shouldn’t, however, come as a great surprise. He endorsed Democrat Joe Biden in 2020 and helped launch a "Republicans for Biden" effort. He also immediately denounced the Jan. 6, 2021, insurrection attempt by Trump supporters and criticized Trump for his role in fomenting it.
