By the way, last June a majority of Republicans in the House voted against a bill that would have installed bomb detection systems at airports.

Republicans have cast votes against the key TSA funding measure that the 2010 appropriations bill for the Department of Homeland Security contained, which included funding for the TSA, including for explosives detection systems and other aviation security measures. In the June 24 vote in the House, leading Republicans including John Boehner, Pete Hoekstra, Mike Pence and Paul Ryan voted against the bill, amid a procedural dispute over the appropriations process, a Democrat points out. A full 108 Republicans voted against the conference version, including Boehner, Hoekstra, Pence, Michelle Bachmann, Marsha Blackburn, Darrell Issa and Joe Wilson.

The conference bill included more than $4 billion for “screening operations,” including $1.1 billion in funding for explosives detection systems, with $778 million for buying and installing the systems.
