Donald Trump is threatening once again to run for president. The famed business mogul recently said that he will announce his presidential plans in June, and that they will “surprise a lot of people.”

Trump has dropped hints on Twitter and in interviews with various media outlets. He has hired staff and visited key primary states. That said, he’s seemingly been flirting with running for president off and on since about 1999. Many pundits and voters no longer take him seriously.
