Senate Majority Leader Harry Reid (D-Nev.) continued to use a procedural maneuver to bring small batches of amendments to a Senate farm bill Wednesday, swatting away a request by Sen. Tom Coburn (R-Okla.) to offer a larger bundle of amendments.

Shortly after the Senate voted down two farm bill amendments, Reid used a floor maneuver called “filling the tree” to bring up four more amendments.

On Tuesday he used the same maneuver to block Sen. Rand Paul (R-Ky.) from offering an amendment to the farm bill, the Agriculture Reform, Food and Jobs Act of 2012 (S. 3240), that would have defunded U.S. aid to Pakistan contingent on the release of a Pakistani doctor who helped the CIA find Osama bin Laden.
