WASHINGTON (AP) — President Barack Obama's orders to change some U.S. surveillance practices have put the burden on Congress to deal with a national security controversy that has alarmed Americans and outraged foreign allies.

Yet he also avoided major action on the practice of sweeping up billions of phone, email and text messages from across the globe.

In a speech Friday, Obama said he is placing new limits on the way intelligence officials access phone records from hundreds of millions of Americans — and was moving toward eventually stripping the massive data collection from the government's hands.

His promises to end government storage of its collection of data on Americans' telephone calls — and require judicial review to examine the data — have been met with skepticism from privacy advocates and some lawmakers.
