From the story here:
Sources said the spying had been going on under President Barack Obama . . .. In October of 2016, Rep. Sean Duffy, the chairman of the House Subcommittee on Oversight and Investigations, sent a letter to then-Treasury Secretary Jacob Lew asking for OIA’s legal authority to collect and retain domestic information.
Nearly one year later, the Congressman has yet to receive an answer, according to a committee staffer.
