Donald Trump said Tuesday that new revelations from WikiLeaks establish that President Barack Obama is 'caught up in the big lie' surrounding the secret server that held all of Hillary Clinton's emails while she was secretary of state.

The president 'claimed to have no knowledge whatsoever of Clinton's – Hillary Clinton's – email server,' Trump recalled as he spoke to nearly 10,000 people assembled on a central Florida airfield.

'"I have no knowledge of it! I don't know!" Trump mugged, doing an Obama impression.

'This guy! He's as bad as she is!'

A Wikileaks email chain published online hours earlier showed Clinton's senior aides knew Obama had received emails from the private address she used to conduct government business. The president, however, claimed he learned about its existence in news reports.

The email, one of thousands hacked from Clinton campaign chairman John Podesta's account, memorializes campaign insiders' surprise when the president played dumb during a CBS News interview.

Donald Trump blasted President Barack Obama on Tuesday, suggesting that he lied last year about his knowledge of Hillary Clinton's secret email setup

Obama said in an interview with CBS News in 2015 that he only learned about Clinton's private server when journalists broke the news

Trump spoke to thousands about Obama on an airport tarmac in Sanford, Florida: 'This guy! He's as bad as she is!'

'Jen you probably have more on this,' Clinton national spokesman Josh Schwerin wrote to communications director Jennifer Palmieri on March 7, 2015, 'but it looks like POTUS just said he found out HRC was using her personal email when he saw it in the news.'

The interview had not yet aired when the email chain began.

Traveling press secretary Nick Merrill forwarded the message to Cheryl Mills, who raised a red flag with Podesta three hours later.

'[W]e need to clean this up - he has emails from her - they do not say state.gov,' wrote Mills, who was Clinton's lawyer and served as her chief of staff at the State Department from 2009 to 2013.

In the interview, CBS News senior White House correspondent Bill Plante asked Obama when he learned about Clinton's private email system.

'The same time everybody else learned it, through news reports,' the president replied.

But Mills' email to Podesta indicates the president had already exchanged emails with his onetime secretary of state at her 'clintonemail.com' address.

In Sanford, Florida, Trump interpreted the story's tea leaves for his cheering – and then booing – supporters.

Clinton campaign spokesman Josh Schwerin emailed communications director Jen Palmieri after the interviwe was taped but before it aired, suggesting the president hadn't been honest

After receiving a copy of Schwerin's email, Clinton lawyer Cheryl Mills told campaign chairman John Podesta that 'we need to clean this up' since 'he has emails from her' that were not sent from an official government email account

'In other words,' he explained, 'Mills was saying – Obama, he had to know that Hillary was using an illegal server, but he claimed otherwise.'

'So that means Obama is now into the act. And now I understand that despite his hatred of the Clintons – 'cause I know one thing, Bill hates him! – but despite his hatred, now I understand why he pushed her.'

'Because he didn't want to be caught up in the big lie,' Trump said.

'He's caught up now, folks.'

White House press secretary Josh Earnest began the clean-up a day after the CBS interview aired in 2015, conceding that Obama had Clinton's private address, but suggested the president never thought it was operated without government oversight.

Hillary Clinton, the Democratic nominee for president, has never been able to shake accusations that she deleted tens of thousands of emails that should have been archived by the State Department, specifically in order to hide pay-for-play corruption in her office

'The president, as I think many people expected, did over the course of his first several years in office exchange emails with his secretary of state,' Earnest said then.

'The point that the president was making is not that he didn't know Secretary Clinton's email address. He did'

'But he was not aware of the details of how that email address and that server had been set up,' Earnest insisted, 'or how Secretary Clinton and her team were planning to comply with the Federal Records Act.'

Clinton ultimately appeared to violate that law by failing to archive every work-related message she sent and received while she was America's top diplomat.

Her lawyers deleted more than 33,000 emails, after keyword searches indicated that they were not about her role at the State Department.

But the FBI, which was later able to scour her homebrew server, discovered hundreds of work-related messages that Clinton failed to submit to State for archiving.

Donald Trump has claimed on the presidential campaign trail that Clinton purposely deleted thousands of emails in order to cover up 'pay for play' arrangements involving favors for foreign governments that contributed to her family foundation or paid her husband six-figure speaking fees.

Those emails that were turned over to the State Department have been released to the public following a review to mask classified information.

Thousands of emails contained such sensitive material, including a few that were classified at the 'Top Secret' level or above.
