(CNN) - There is one more sign Donald Trump is preparing to become a presidential candidate.
The real estate mogul told CNN's National Correspondent Susan Candiotti that his accountants are already hard at work on the financial paperwork required of candidates.
"They're in the process," he said in a Friday phone interview. Trump continued to say he won't disclose his net worth until he announces whether he's running.
"I don't want to ruin the suspense," he said.
Trump promised the financial forms would be released "simultaneously" with any potential announcement to run for President. Asked whether the prying forms have been uncomfortable for him to answer, Trump shot back, "nothing makes me uncomfortable."
