Asked by NewsmaxTV's Steve Malzberg why he hadn't yet endorsed Donald Trump, Sen. Mike Lee (R-Utah) offered three reasons: Trump's suggestion that "best friend" Ted Cruz's father was involved in the John F. Kennedy assassination, that Trump's "made statements that some have identified correctly as religiously intolerant," and that he's "wildly unpopular" in Utah, a state with "people who are members of a religious minority church" and thus rightly nervous about Trump. A poll in early June showed Trump and Hillary Clinton tied in Utah with Libertarian Gary Johnson at 14 percent. Utah last voted for a Democrat for president when it chose Lyndon Johnson over Barry Goldwater in 1964.

"I could go on if you'd like," Lee offered, before saying Trump's statements were not something he couldn't get over, provided he "heard the right things" from Trump. Lee said he hoped he could "get over these concerns" and that "Trump can help me identify them."
