I read a news article today that claims that a Congressional bill to provide disaster relief to US communities has been derailed, because a single member of the House of Representatives objected to it.
How is it possible for a single member of congress to effectively 'veto' an entire bill like this? I thought most (if not all) votes in Congress are decided by majority vote. Was this vote different for some reason, which meant it had to be unanimous? (if so, why?)
