Sen. Dan Sullivan said whether Trump gets indicted as he runs for president is a "huge hypothetical".
Without endorsing or refusing Trump, Sullivan said on ABC News he plans to support the GOP nominee.
"I think what's happening, though, within the Republican Party right now, in terms of presidential candidates, is healthy, right?"
"We not only have President Trump, but we have a number of other, I think, very qualified candidates who are throwing their hat in the ring."
"I think you're going to see some others throwing their hat in the ring very soon," Sullivan said on "This Week".
