DOJ wanted to track James Rosen's emails "indefinitely"

From the UPI:

U.S. prosecutors asked a judge to defer indefinitely notifying a Fox News reporter his email was being monitored in a national security probe, records indicate. 

Court documents unsealed this week show U.S. Attorney for the District of Columbia Ron Machen argued in 2010 the normal practice of notifying people of such monitoring within 30 days should not apply to James Rosen, who was being investigated in a national security leak case, The Hill reported Friday. . . .
