The head of the National Security Agency defended

his beleaguered organization, saying it acts within the law to

stop militant attacks and calling reports that the NSA collected

data on millions of phone calls in Europe false.

The intelligence chiefs appeared against a backdrop of

angry accusations by European allies that the United States

spies on their leaders and citizens, accusations prompted by

highly classified documents that Snowden leaked to media

organizations.

Army General Keith Alexander, testifying with other

U.S. spy chiefs before the House of Representatives

Intelligence committee, sought to defuse a growing controversy

over reports of NSA snooping on citizens and leaders of major

U.S. allies.

The hearing took place as Congress is weighing new

legislative proposals that could limit some of the NSA's more

expansive electronic intelligence collection programs.

More than any previous disclosures from the Snowden

documents, the reports of spying on close U.S. allies have

forced the White House to promise reforms and even

acknowledge that America's electronic surveillance may have

gone too far.
