There are fresh revelations this morning after WikiLeaks released a new batch of Clinton campaign chairman John Podesta's hacked emails.

An email from 2015 shows Hillary Clinton's top aide and lawyer Cheryl Mills writing to Podesta, "we need to clean this up," an apparent reference to communications between President Obama and Hillary Clinton in which she had used her private email server. 

"He has emails from her - they do not say," Mills continued.

The email from March 7, 2015 was sent after news broke that Clinton had used the private server while she was secretary of state. 

Obama said in multiple interviews that he didn't know Clinton was using the private server and learned about it from news reports.

Ed Henry reported the latest details this afternoon, pointing out another Podesta email in which he and Mills talked about emails to and from the president. 

As Republicans in Congress moved to subpoena the emails, Podesta wrote: "Think we should hold emails to and from potus? That's the heart of his exec privilege. We could get them to ask for that. They may not care, but I(t) seems like they will."

Henry said the emails suggest that President Obama may have known more than he said.

Bret Baier reported today that the White House has maintained that although Obama knew Clinton's email address, he did not know the details on how the server was set up.

In a CBS interview in March 2015, Obama was asked when he first learned about Clinton's private server that she used as secretary of state. 

"The same time everybody else learned it through news reports," he answered.

The new email comes on the heels of a report that revealed top Clinton ally Virginia Gov. Terry McAuliffe’s PAC gave nearly a half-million dollars to the state senate campaign of the wife of an FBI official who would go on to help oversee the Clinton email probe.
