Brent Wilkes' "Secret Benefactor" will have to make himself known if he wants to help the convicted former-defense contractor make bail, a federal judge said Monday.

You might remember that we posted a few weeks back about an anonymous ally's guarantee on the balance of the $1.4 million Wilkes needed to make bail pending appeal. But there was a catch-- the benefactor wouldn't post unless his identity could be kept a secret-- so Wilkes' attorneys went to court to try to hide the man's identity.

From the San Diego Union-Tribune:

The man willing to make up the shortfall could lose his job if his name is linked to Wilkes, said lawyer Robert Rexrode, who is representing Wilkes for free.

"This is it," he said in court. "It's not going to happen if the name is public."

Rexrode wouldn't say what the man does for a living but said that the public attention that Wilkes has drawn "makes it difficult for past business associates to come forward."

Judge Larry Burns said he was willing to keep certain financial details private, but not the man's name.

"This person ... has to step up and stand here with Mr. Wilkes," Burns said.
