Mueller places sealed document in vault on the same day Cohen’s congressional testimony delayed
Robert Mueller (

A sealed document was placed in a vault as part of the special counsel case against former Trump Organization attorney Michael Cohen.

Courthouse News reporter Adam Klasfeld noted the docket activity Wednesday, the same day Cohen's congressional testimony was delayed "in the interests of the investigation" until Feb. 28 by House Intelligence Committee Chairman Adam Schiff (D-CA).

Cohen, who has pleaded guilty and agreed to cooperate with special counsel Robert Mueller, had been scheduled to testify before the committee Friday in a closed-door session.

It's not clear what the sealed document might be, but it was part of the Mueller docket, and not the Southern District of New York, where Cohen also has a cooperation agreement.
