Former GOP Sen. Jeff Flake detailed his reasoning for throwing his support for Democratic presidential nominee Joe Biden, saying that the former vice president upholds traditional institutions.

“Conservatives believe in preserving institutions, to preserve what we know works and the institutions of American democracy — our freedom of the press, for example, or separation of powers, an independent judiciary,” Flake said in an interview with CNN’s Christiane Amanpour. “The president has shown that he little understands or little appreciates these institutions.”
