A federal judge in Virginia just sealed the courtroom for a hearing for Damaso Lopez, Chapo Guzman's longtime top aide.
Prosecutors are expected to ask the judge to reduce Damaso's life sentence for testifying against Guzman at his trial last year.
The US govt apparently doesn't want anyone knowing about the deals they cut in w/cartel informants.
Federal prosecutors seem not to want to reveal what benefits they are giving to him for helping them make their landmark case against Chapo.
