Property mogul and TV showman Donald Trump has fuelled more speculation that he would enter the 2012 White House race with an expletive-laden speech in which he attacked America's "stupid" leaders.
He assured a crowd of supporters at a Las Vegas casino that he was seriously considering a presidential run.
The setting was fitting for the casino king whose moniker is draped across the gold-tinged Trump International Hotel & Tower just off the Las Vegas Strip.
An open bar greeted more than 1,000 people, waiters passed hors d'oeuvres, and a Trump impersonator entertained the crowd.
At one point, a woman in the lavish reception at the Treasure Island casino shouted out that Mr Trump should run for president. "I think I am going to make you very happy," the developer said.
But he later said: "There is a real good chance that no matter what happens I won't win because one of these blood-sucking politicians who's been bull*****ing people for years will end up still getting elected."
During a 30-minute stump speech focused mostly on foreign affairs, Mr Trump sprinkled in a number of swear words and insults directed towards global leaders. "Our leaders are stupid, they are stupid people," he said. "It's just very, very sad."
Mr Trump also blasted President Barack Obama's handling of Libya, Iraq, China and Afghanistan, and in one of his many curse-bombs, he lamented the nation's focus on building schools in war-torn Afghanistan while neglecting education in the US.
He said he would not help struggling nations such as South Korea, Iraq or Libya without payment. "I'm interested in protecting none of them unless they pay," he said.
Mr Trump has created waves by questioning whether the president was born in the US. Mr Obama produced his detailed Hawaii birth certificate on Wednesday and Mr Trump eagerly took credit for the revelation.
