The Democratic leader of the Senate Intelligence Committee said Monday that the White House appears to be responsible for some leaks of classified information.

“I think the White House has to understand that some of this is coming from their ranks,” Sen. Dianne Feinstein told a World Affairs Council forum.

The California lawmaker said she was certain that President Barack Obama, who receives a daily intelligence briefing, isn’t disclosing secret information, but she was uncertain about others at the White House. “I don’t believe for a moment that he goes out and talks about it,” she said.

Republicans have criticized the disclosures, arguing that members of the Obama administration were intentionally leaking classified material to enhance the president’s reputation in an election year. Attorney General Eric Holder has appointed two attorneys to lead the investigation into who leaked information about U.S. involvement in cyberattacks on Iran and about an al-Qaida plot to place an explosive device aboard a U.S.-bound airliner.

That hasn’t satisfied some Republicans who have pressed for a special prosecutor.

Last Thursday, Defense Secretary Leon Panetta and Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, testified in closed session before the House Armed Services Committee on the leaks. The committee’s chairman, Rep. Howard “Buck” McKeon, R-Calif., told reporters afterward that he did not believe the Pentagon was responsible for recent national security leaks.
