I wish I could say I'm shocked by this, but I'm not. From Current's The Young Turks: Did Fox News host Sean Hannity offer to pay for George Zimmerman’s defense? :

Cenk talks to GlobalGrind.com editor-in-chief Michael Skolnik, who discovered that in George Zimmerman’s jailhouse tapes he references someone he calls “S.H.” who might help pay for his defense. Could it be Sean Hannity, who has had off-the-record conversations with Zimmerman before? Fox News denied that Hannity has contributed financially, but Skolnik says a “rock solid source” confirms at least some of the story.

Here's more from GlobalGrind.com: SHOCKING REVELATION! Fox News Host Sean Hannity Offered To Pay George Zimmerman's Legal Fees!:

Yesterday, the Special Prosecutor in the George Zimmerman case released 149 jail house phone calls that Mr. Zimmerman made while being held on bail in April of this year in Seminole County Jail. Last night, GlobalGrind scoured through all of them, trying to decipher the coded language that George uses in his conversations with his family and close friends.

In call #30, from April 14th (3 days after being arrested), George is speaking to one his closest friends and confidantes, "Scott." As reported by many of our colleagues in the press, including the Miami Herald this morning, George mentions to Scott that his attorney Mark O'Mara is aware of an attempted transfer of $37,000 from his PayPal account to Zimmerman's wife's personal account. This would be big enough news in the case, as Mr. Zimmerman was sent back to jail after being released on his first bond for not disclosing the amount of money he had raised for his legal defense fund. Furthermore, Mr. O'Mara admitted in court that he did not know anything about the attempted transfers, but with this new evidence being made public, it seems that the attorney was in the know.

However, as we listened to the rest of the call, what struck us as odd was George's comments about a gentleman, who he calls "SH," who offered to pay for his entire legal defense, as long as he uses an attorney, who George calls "JB." In a previous call (#24), George reveals to his wife, Shellie, that "JB" is Jose Baez, who represented Casey Anthony (this was also confirmed to GlobalGrind by Miami Herald reporter, Frances Robles). However, the person who offered to pay for his legal fees, "SH" is only identified in code.

More there with transcripts of the phone recordings and from the end of the article:

George Zimmerman decided not to use Jose Baez as his attorney and stuck with Mark O'Mara. We do not know if Sean Hannity is funding Mr. Zimmerman's legal defense with Mr. O'Mara at the helm. We reached out to Mr. Hannity for comment and are awaiting a response.
