The U.S. Senate renewed the warrantless wiretapping program begun during the George W. Bush administration by a 73 to 23 vote on Friday, sending the FISA Amendments Act to President Barack Obama's desk for his signature.

The vote marked a symbolic next step for the wiretapping program, which collects Americans' communications with foreign intelligence targets abroad. Four years ago, in the midst of the 2008 Democratic presidential primary, an identical version of the bill was the subject of a highly contentious debate in the Senate. Obama and others argued then that Bush's program went too far in violating Americans' privacy. This year, with a supportive Obama in the Oval Office and the media focus on the fiscal cliff, the bill was renewed with much less attention.
