This is sort of history making. There's been one filibuster in the history of the U.S. that lasted 24 hours. This one being led by Sen. Rand Paul and now Sen. Ted Cruz (R-TX) is going into it's 11th hour.
A filibsuter is simply a tactic that includes "talking a bill to death." What this is meant to do is exhaust everyone into delaying a vote on a particular bill. In some cases, completely taking the bill off the floor entirely.
What this is mainly in response to is President Obama's and Attorney General Eric Holder's positions on assassinating American citizens with drones, both OFF AND ON U.S. soil.
Thoughts? Critiques? Regardless, we haven't seen this done for quite some time, at least not to where it garnered this much attention. #StandWithRand is surging on Twitter right now and has been for a number of hours.
Edit: Sorry, didn't see the other thread(s) pertaining to this issue.
