Not so. The program everyone's complaining about this week collects only metadata, but on fully domestic calls. The "warrantless wiretapping" program was targeted at actual content, but also at cases where one party was believed to be outside the United States. Of course, the Obama NSA has continued the latter program as well, under the statutory authority of the FISA Amendments Act of 2008, which Obama himself voted for as a Senator. You can claim they have "warrants" now, since the FISA court has issued a warrant approving the program, though not individual wiretaps.
