What part of the constitution gives congress the authority to stretch its power beyond what is in the constitution? concurrent powers elastic clause tenth amendment none of the above

The answer for this would be the third option: TENTH AMENDMENT. The Tenth Amendment of the United States basically states not any power that is not covered by the federal government is extended towards the states or to its people. Hope this answer helps.

The principle that george w. bush used to keep white house communications confidential would be executive privilege. but i maybe wrong : )
