As Democratic presidential nominee Hillary Clinton’s campaign spends money on TV ads in red-state Arizona, Republican nominee Donald Trump on Sunday resumed his feud with one of Arizona’s Republican senators.
U.S. Sen. Jeff Flake appeared on two national Sunday morning public-affairs programs — CBS’ Face the Nation and CNN’s State of the Union — to discuss Trump, whom he has thus far refused to endorse because of the candidate’s harsh anti-illegal-immigration rhetoric and lack of serious policy proposals. On Sunday, Flake would not commit to voting for Trump. Flake also has said Trump’s controversial statements have put Arizona in play for the Democrats this year.
