I do know what the word means, do you know what both the NSA and FISA courts have been doing which compromises the integrity of our Democratic Republic form of Government? You do not see how smear campaigns based on illegally obtained information breaks the Democracy?
Yes they are treasonous, do some homework.
From TFC (The F**king Constitution):
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.
Note that "break the Democracy" and "compromises the integrity of our Democratic Republic form of Government" are not mentioned there.
So, no, they're not treasonous.
Even if they were treasonous, finding two witnesses to the same overt act might be a bit tricky, since you'd first have to define a specific overt act that was treasonous, then find two people willing to admit to witnessing the act.
