On Friday the entire fifth floor of a Washington D.C. court room was shut down, so that investigators in Special Counsel Robert Mueller's probe could obtain a subpoena in secrecy.

Journalists were shooed away, Politico reported, and hungrily waited for scoops—apparently none came.

As Mueller's team waged battle behind closed doors, there was speculation that Trump himself was the target of the subpoena.

“At every level, this matter has commanded the immediate and close attention of the judges involved — suggesting that no ordinary witness and no ordinary issue is involved,” former federal prosecutor Nelson Cunningham wrote in Politico previously.

Another legal analyst told Politico that the secretive probe was odd.

“It’s not the norm, that’s for sure,” Manuel Retureta, a Washington-based defense lawyer said.
