The NSA cannot intercept all communications.  For the NSA and overseas intelligence to trace data, they must explain how data was first obtained, then used for subsequent searches.

FOIA Request

In your FOIA request of the NSA, ask how data, illegally obtained, is repackaged, and repositioned under the umbrella of another program.  The allegedly illegally captured data is then allegedly searched illegally, then allegedly provided as investigative leads to civilian law enforcement.

The Senate and House Intelligence Committees will have to explain why they have not asked for detailed, step-by-step examples of how a specific data intercept was or wasn't linked to a US citizen communication or electronic activity. This has not been adequately done.
