(CNN) -- Real estate mogul and television celebrity Donald Trump, who generated a media publicity blitz by saying he might run for president in 2012, announced Monday that he will instead remain a businessman.
"After considerable deliberation and reflection, I have decided not to pursue the office of the presidency," Trump said in a statement.
With his typical bravado, Trump maintained that he would have won the Republican primary and the general election, but recognized that "running for public office cannot be done half-heartedly."
"Ultimately, however, business is my greatest passion and I am not ready to leave the private sector," Trump said in the statement.
Trump's flirtation with running for the Republican nomination included his demand that President Barack Obama make public his full birth certificate from Hawaii.
Obama previously had provided a shorter version that serves as the public record in Hawaii, but amid the media glare on the issue raised in part by Trump's repeated questioning of whether the so-called long version of the document existed, the president released it last month.
