This is literally old news - contemporaneous with Snowden, Prism, etc. in early 2000s. Go read about the current Section 702 / FISA authorization renewal battle about which Senator Wyden recently said:
“I strongly believe that this matter can and should be declassified and that Congress needs to debate it openly before Section 702 is reauthorized,” Wyden said in a Senate floor speech last month. “In fact, when it is eventually declassified, the American people will be stunned that it took so long and that Congress has been debating this authority with insufficient information.”
