Senator Romney may never endorse President Trump’s re-election

Senator Mitt Romney says he may never endorse President Trump's re-election.

Romney made the comment Friday at the E-2 Summit on policy and politics at Stein Erikson Lodge in Deer Valley.

Romney told an audience of 250 business leaders he thought Trump would be the Republican nominee, but that his winning the election wasn't a sure thing.

He also said Joe Biden was a better Democratic challenger than Bernie Sanders.
