This memo proves that this is not what they are after. They want to be given access into other areas to search for anything they think they could possibly use against the administration, going beyond they intellegence they have been given to not help America and their soldiers but to bring down a sitting president for no other reason other than political gain.
That goes beyond the scope of the intellegence committee without any evidence of wrong doing, but just a political mission on their part that happens to coincide with our enemies. That is aiding and abetting an enemy (because there is no cause but their getting their power back and not any pursuit of known wrong doing), thus it is treason or as Zell said its close cousin.
