As a senator, Obama wanted to limit bulk records collection.

Obama co-sponsored a 2007 bill, introduced by Sen. Russ Feingold, D-Wis., that would have required the government to demonstrate, with „specific and articulable facts,“ that it wanted records related to „a suspected agent of a foreign power“ or the records of people with one degree of separation from a suspect. The bill died in committee. Following pressure from the Bush administration, lawmakers had abandoned a similar 2005 measure, which Obama also supported.
