Former Republican presidential candidate Mitt Romney declined to rule out — and in — a run for a Senate seat in the future.

"I don't have any predictions on what I might do. I'm not going to open a door and I'm not going to close a door. All doors are open," Romney said in an interview the Deseret News.

Utah Sen. Orrin Hatch, R, — who has been in office since 1976 — has not yet said whether he will run for re-election in 2018.

The names of former Gov. Jon Huntsman Jr., as well as one of Romney's own sons, Josh Romney, have already been floated as possible candidates.

Romney added: "I'm not looking forward to anything political at the national level. We've got some races coming up here in Utah that are going to be interesting. We'll see what happens on that front."

The 2012 GOP candidate said he has no regrets about criticizing then candidate Donald Trump in March, but now sees the president as having "obviously gotten off to a very strong start."

"I expressed honestly what my belief was with regards to temperament and character. Now the time has come for us to recognize we have a new president and we have hopes he will be successful leading our country," Romney said.

Romney had been in the running to be picked as President Trump's nominee for secretary of state, after speaking very critically of the billionaire businessman during the presidential campaign. Trump later chose retired Exxon CEO Rex Tillerson, who was confirmed by the Senate this week.
