Trump previously considered presidential bids in 1988 and again in 1999, but eventually decided not to run both times. This time around critics remain skeptical about his intentions, speculating that he is just trying to garner favorable publicity for his many media and business ventures.
New Jersey Gov. Chris Christie expressed skepticism ove a Trump presidential candidacy during an interview Wednesday with ABC News anchor Diane Sawyer.
"Donald's a really good friend of mine. I don't know that Donald really wants to be president," he said.
"We've spoken about it, and all I can say to you is that, you know, I'll believe it when I see it," Christie said. "I think he likes what he does. I think he likes building things. And I think he likes being on TV, and you know, he does that well."
Referring to Trump's hints about running, Christie added, "I wouldn't call it stunt, but I think he's very outspoken and... he loves to be on the stage and to express his opinions."
Even so, Trump has scheduled speaking appearances in two important early nominating states -- Iowa and New Hampshire -- in June, the same both he has said he will announce his decision about the 2012 race.
