Continuing a program first launched under former President George W. Bush, President Obama allowed the National Security Agency to secretly gather email and internet usage data from Americans for more than two years, according to a new report from the Guardian.

Under the program, first approved by a FISA court judge in 2001 and renewed every 90 days, the NSA collected internet metadata, but did not review the content of emails vacuumed up in the trawling. An administration official told the Guardian the program ended in 2011.

More from the Guardian:

The internet metadata of the sort NSA collected for at least a decade details the accounts to which Americans sent emails and from which they received emails. It also details the internet protocol addresses (IP) used by people inside the United States when sending emails — information which can reflect their physical location. It did not include the content of emails. [Guardian]

It's the latest in a string of revelations into the administration's wide-ranging, clandestine security operation. Previous reports disclosed that the government has snooped around Americans' cell phone records, and unveiled the data-mining PRISM program.
