Interestingly in 2015, AG to be Sessions introduced an amendment that "would have exempted federal agents from the requirement to secure a warrant if the government asserts that an emergency situation exists."
The bill was then withdrawn from consideration.
Is there something similar attached to the current version?

The only differences I saw are that it's now a BILL instead of an ACT, and they added the word "and" in one spot.
As far as I can tell the amendments were not actually voted on last year; the bill was preemptively withdrawn because the sponsors thought passing a bill with the amendments would be worse than not passing it at all.
