Donald Trump is expected to make a big announcement Tuesday, and many speculate he's running for president. Reuters

Donald Trump, the billionaire real estate mogul known for bringing you the television program "The Celebrity Apprentice” and the catchphrase “you’re fired,” is expected to announce his bid for the White House Tuesday from one of his Manhattan towers. Trump is also expected to release details about his personal wealth, which is reported to be somewhere near $9 billion.

According to the Washington Post, during his announcement, he will provide a two-page document that adds up the valuation of his various hotels and real estate properties. Trump, who has never held elected office, will be joining an already crowded Republican field that now includes the respective son and brother of two former presidents, four U.S. senators and three former governors. Trump would also not be the only corporate CEO in the race: Carly Fiorina was the head of Hewlett-Packard in the early 2000s.

Trump is expected to play up his personal fortune as a qualifying credential for the White House. In an interview reported earlier this month, Trump reveled in his success and took a jab at the most recent Republican nominee, Mitt Romney. “I'm the most successful person ever to run for the presidency, by far," said Trump. "Nobody's ever been more successful than me. I'm the most successful person ever to run. Ross Perot isn’t successful like me. Romney — I have a Gucci store that’s worth more than Romney,” he said.

Trump almost ran for president in 2012, and his unofficial campaign drew a lot of attention. While he ultimately declined to seek the Republican nomination, he received plenty of press for repeatedly implying that Barack Obama wasn’t qualified to be president because he was not born in the United States. Ultimately, though it became a sticking point for many, Obama released the long-form version of his birth certificate and effectively put the issue to rest. Trump decided not to run one month later after repeated ridicule for the “birther” issue.

Trump often bragged about coming in first in national polls and did so when he announced he was declining to run in 2012. At the time of his announcement not to run for president, however, at least one poll said that 71 percent of those surveyed for a Politico/George Washington University poll thought he had no chance of winning.

In 2012, he said he wasn’t going to run for the White House so that he could stay in the private sector and continue his television show. In March of this year he left “Celebrity Apprentice” and formed an exploratory committee to feel out a run for the office.

“I am the only one who can make America truly great again,” he said in a statement at the time.
