A close confidante of Hillary Clinton's campaign chairman was convinced she 'wanted to get away with' keeping all her official emails on a private homebrew server, according to a stolen email released Tuesday by WikiLeaks.

In the message chain, Center for American Progress president Neera Tanden told Clinton chairman John Podesta – who was also the far-left group's board chairman – that Clinton should 'immediately' move to hand her entire email archive over to the National Archives.

The conversation came one day after The New York Times first published evidence of the former secretary of state's controversial email setup, which put her work-related correspondence outside the reach of officials who responded to Freedom of Information Act requests.

'Why didn't they get this stuff out like 18 months ago? So crazy,' Tanden said.

Podesta responded, calling foot-dragging by Clinton and her lawyers Cheryl Mills and David Kendall 'unbelievable.'

'[I] guess I know the answer,' Tanden chimed in, answering her own question.

'[T]hey wanted to get away with it.'

Mills and Kendall, along with former Clinton spokesman Philippe Reines 'sure weren't forthcoming on the facts here,' Podesta fumed.

In addition to counseling her legally, Mills was Clinton's chief of staff at the U.S. State Department from 2009 to 2013.

'This is a [C]heryl special,' Tanden griped.

'[I] know you love her, but this stuff is like her Achilles heal [sic]. Or kryptonite. [S]he just can't say no to this s**t.'

Podesta has become a liability to Clinton as secret after secret from inside her White House run has been leaked to the public following the hack

The WikiLeaks disclosure is part of a trove of thousands of Podesta's emails that were hacked from his account this year.

The Obama administration has pointed a finger at Russian intelligence services, claiming Vladimir Putin's government is plotting to prevent Clinton from winning the White House.

Clinton's email saga began in March 2015 and has spiraled into multiple congressional investigations and a lengthy FBI probe.
