President Barack Obama denies that the White House has deliberately leaked classified national security information that is flattering to him.
Obama said the allegations, from Republican critics, are "offensive" and "wrong." He promised investigations into the source of leaks about U.S. involvement in cyber-attacks on Iran and drone strikes on suspected terrorists.
Obama said his administration has "zero tolerance" for such leaks and that there would be an internal administration probe. The strongest claims came from Obama's 2008 election opponent, Republican Sen. John McCain of Arizona. Attorney General Eric Holder appointed two U.S. attorneys to lead a pair of criminal investigations into possible unauthorized disclosures of classified information. (AP)
