Gov. Chris Christie has criticized Hillary Clinton in recent days over her use of private email to do State Department business. But the only email he provided to the Legislature last year came from his private Yahoo account.

Christie turned over just one set of emails to the New Jersey Legislature in response to its subpoenas about Bridgegate. That email conversation contained edits that Christie made to a statement announcing the resignation of Port Authority official David Wildstein, who has since pleaded guilty for his role in the lane closures.

Democratic Assemblyman John Wisniewski, who led the investigation, told WNYC that Christie sent those emails in December 2013 from his personal Yahoo account. The public documents had previously been released but the email address was blacked out.

Christie has said Clinton's use of a private email account was done to avoid public scrutiny.

"Can you imagine, if after the bridge investigation began, I came out and said 'Oh, I've done all my business as governor on a private email server. And, I've deleted now 30,000 of those emails. But trust me none of it had to do with the bridge.' Give me a break," Christie said Monday on CNN. 

Both New Jersey and federal guidelines say government business should not be conducted over personal email accounts, which can be obscured from the public. 

But Christie insists Clinton's transgression is unique in that she maintained a private server in her home that may have contained thousands of emails with classified information. Christie has also said that he held a press conference that lasted nearly two hours to answer questions about Bridgegate, while Clinton has joked off the email controversy.
