Over the course of his filibuster yesterday, Rand Paul used the word "drone" in a military context more than any two-year Congressional term in history — and more than it had been used in the Congressional Record prior to the 112th Congress, combined.

While he was speaking, some of those following along on Twitter wondered if this was the lengthiest discussion of drones that had ever occurred in Congress. Searching the official transcript of Congressional business reveals that it was, by far.

In total, Paul (and, to a lesser extent, other Senate speakers) said the word 489 times — 22 percent more than the term had been used on the record in the preceding twelve years.

Discussion of drones has only occurred in earnest over the past two years. The most recent Congress mentioned drones 241 times, a figure Paul surpassed before suppertime.
