Call your representative's office (http://www.house.gov/representatives/find/) and tell him to vote for the Amash Amendment to HR 2397 (citing the bill number signals seriousness) and point out that the data for the call is being recorded by the NSA (seriously: the one blanket metadata warrant we've seen is for Verizon's Business unit, which as the D.C. ILEC we can assume provides the Capital Hill land lines).
The guy who answered the phone this morning groked "including the data about this phone call", said the office had been getting quite a few calls on it, and said he'd add me to the tally.
