Former New York City Michael Bloomberg expressed interest in being secretary of state under Hillary Clinton, according to emails released by WikiLeaks.

A new batch of emails unearthed by the site reveals that a senior advisor to the billionaire mogul was in contact via email with an associate of Clinton's last year when rumors were abound that Bloomberg was mulling a run for the White House.

Neera Tanden, a longtime confidante of Clinton's, asked Howard Wolfson, a senior adviser to Bloomberg, 'what is up' with reports that Bloomberg was thinking of throwing his hat in the ring.

Wolfson, who helped Clinton win election to during her campaign to represent New York in the US Senate in 2000, said that the reports which surfaced in June 2015 were 'laughable.'

Tanden replied by inquiring as to which positions Bloomberg would be interested in filling under a potential Clinton administration.

'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.

Tanden then forwarded the message to John Podesta, the chairman of Clinton's presidential campaign, writing that Bloomberg's interest in being the country's top diplomat was 'something to know for down the road.'

Wolfson denied that Bloomberg was angling for the secretary of state position.

'I think Mike made it pretty clear over the last year that the job he wanted was the top job,' he told US News and World Report.

Wolfston was asked by Tanden if there was a job in a future Clinton administration that would interest Bloomberg. He replied 'sec of state'

When asked what he meant by 'top job,' Wolfson replied: 'POTUS'.

Bloomberg currently holds the title as UN Secretary-General Ban Ki-moon's special envoy for cities and climate change.

Although Bloomberg entered the mayor's office as a Republican in 2001, he dropped his party affiliation and was officially listed as an independent.

Prior to 2001, he had been a Democrat.

During this election campaign, he has endorsed Clinton while calling her Republican opponent, Donald Trump, a dangerous demagogue.

'When I enter the voting booth each time, I look at the candidate, not the party label,' Bloomberg told the Democratic National Convention in Philadelphia this past July.
