Did you actually take the time to look up and read Chapter 36 of Title 50 of the US Code I referenced? Answer - No
If you did read the Code referenced, did you want to believe it as factual?  Answer - no.
Are you trying to deliberately trying to cloud the straight forward issue? Answer ____.

By the way, the statute  reads "through the AG to ACQUIRE foreign intelligence", not "through the Attorney General...AND foreign intelligence". If you need a definition of "electronic surveillance" please let me know.

Seems to me your reading comprehension skills need some work.
