Politico reports President Barack Obama Friday reinforced the perception that a New York Times journalist won't be thrown in jail for refusing to identify his confidential sources for a book that allegedly contained highly classified information provided by a Central Intelligence Agency officer. Asked at a press conference here about the longrunning case involving Times national security reporter James Risen, Obama said he couldn't comment on any pending matter but he pointed to comments Attorney General Eric Holder has made ruling out jailing of journalists for resisting efforts to force them to identify sources. "I can read back to you what Attorney General [Eric] Holder said which is no journalist is going to go to jail for doing their job," the president said. He called the treatment of national security issues and press rights a "balance." He added : "We've got courts and the First Amendment and a whole bunch of tools to ensure that balance is properly debated and adjudicated."
