Holder Personally Vetted Rosen Search Warrant - Government Intended to Monitor Rosen "for many years because, while the evidence is not yet sufficient to bring charges, it is sufficient to have identified criminal subjects and/or criminal activity serious enough to justify continuation of the investigation.”

From the New Yorker:

[The prosecutor, Machen] argued that disclosure of the search warrant would preclude the government from monitoring the account, should such a step become necessary in the investigation. Machen added that “some investigations are continued for many years because, while the evidence is not yet sufficient to bring charges, it is sufficient to have identified criminal subjects and/or criminal activity serious enough to justify continuation of the investigation.” 

As Epa might say, EVERYTHING THAT IS NOT PERMITTED IS A FEDERAL FELONY.

YOUR ATTITUDE HAS BEEN NOTED, MR. ROSEN.

Machen insisted the investigation would be compromised if Rosen was informed of the warrant, and also asked the court to order Google not to notify Rosen that the company had handed over Rosen’s e-mails to the government. Rosen, according to recent reports, did not learn that the government seized his e-mail records until it was reported in the Washington Post last week.
According to recently unsealed documents in the case, the Obama Justice Department sought an extensive amount of information from Rosen’s e-mail account. In addition to Rosen’s correspondence with Kim, the government wanted to know about Rosen’s contacts with other government officials, including “records or information relating to the Author’s communication with any other source or potential source of the information disclosed in the Article.”
