In June 2015, close Clinton associate Neera Tanden messaged Howard Wolfson, a senior advisor to the former New York mayor and business mogul. She asked "what is up" with regard to rumors at the time that Bloomberg was mulling a run for president – potentially against Clinton.

Wolfson, who was instrumental in Clinton's 2000 Senate election as well as a key part of her 2008 presidential run, called the reports "laughable," to which Tanden responded asking what positions in the administration Bloomberg would interested in serving in.

"Is there something Mike Bloomberg would want to do in his life in an Admin? Is like Ambassador to China way too small," Tanden asked.

"Secty of state Which ain't gonna happen," replied Wolfson.

But Tanden forwarded the correspondence to Clinton campaign chair John Podesta, writing, "Something to know for down the road."

When reached for comment, Wolfson denied Bloomberg's specific interest in running State, telling U.S. News, "I think Mike made it pretty clear over the last year that the job he wanted was the top job."

When asked to clarify whether that meant "top job" at State or that Bloomberg only wants to be president, Wolfson replied, "POTUS."

Bloomberg serves now as the U.N. Secretary-General's special envoy for cities and climate change under outgoing Secretary-General Ban Ki Moon.

"America is best when she leads from the front," Bloomberg said in remarks in Washington in 2015. "I think [Secretary of State John Kerry] and the president deserve enormous credit for bringing the full forces of American diplomacy... for recognizing a fundamental truth that was overlooked for too long: We cannot address climate change effectively without putting cities at the center of the agenda."

Bloomberg, who has been a Republican, Democrat and independent in his career, has since endorsed Clinton, and blasted fellow Manhattanite Trump.

"When I enter the voting booth each time, I look at the candidate, not the party label," Bloomberg said in July in an address to the Democratic National Convention in Philadelphia. "There are times when I disagree with Hillary Clinton. But let me tell you, whatever our disagreements may be, I've come here to say: We must put them aside for the good of our country. And we must unite around the candidate who can defeat a dangerous demagogue."

Trump has responded, knocking "little" Bloomberg for never having "the guts to run for president."
