Former President Donald Trump said Monday he will be making a “big announcement” next week as he teased a third presidential run while campaigning on the eve of the final day of voting in this year’s midterm elections.

“I’m going to be making a very big announcement on Tuesday, Nov. 15 at Mar-a-Lago,” Trump said before a cheering crowd in Vandalia, Ohio, Monday night, where he was holding his final rally of the midterm season to bolster Senate candidate JD Vance.

Trump explained that he wanted “nothing to detract from the importance of tomorrow,” even after he had sparked a frantic effort to hold him off after he had told people he was considering officially launching his next campaign Monday night at the rally.

Trump has been increasingly explicit about his plans to seek another term, saying in recent days that he would “very, very, very probably” run again and would be formalizing his intentions “very, very soon.”

“I will probably have to do it again but stay tuned,” he said Sunday night in Miami. “Stay tuned to tomorrow night in the great state of Ohio.”

Republican officials and some people in Trump’s orbit had been urging him for months to wait until after the midterms were over to launch, in part to avoid turning the election into a referendum on him and to shield him from potential blame should Republicans not do as well as the party hopes on Tuesday.
