Moderate Republican Sen. Susan Collins of Maine isn’t saying whether she would support Donald Trump if he ends up being the GOP’s presidential nominee.

Interviewed on Maine radio station WGAN on Tuesday, Collins said she’s always backed the Republican nominee, “but I’m going to wait and see.”

Collins, who was a supporter of former Florida Gov. Jeb Bush, said she hasn’t found someone else to back — and won’t.

“I’m going to let the process play out, I’m not going to make another endorsement,” she said.
