Another issue that frustrated Obama in his first term resurfaced when he was pressed about the hunger strike at Guantanamo Bay, the detention center he promised to close but hasn't been able to. Obama said he would make another run at it, though he was vague about how.
"I'm going to go back at this," he said. "I've asked my team to review everything that's currently being done in Guantanamo, everything that we can do administratively, and I'm going to re-engage with Congress to try to make the case that this is not something that's in the best interest of the American people."
The president also took questions for the first time about the investigation into the Boston Marathon bombings that rattled the nation two weeks ago. He defended the FBI's 2011 investigation into Tamerlan Tsarnaev, the suspect who was killed, a probe that resulted in the bureau finding no evidence that he was a threat to the United States.
Russia has since provided more information about Tsarnaev and his mother — both ethnic Chechens— that could have resulted in a more rigorous FBI investigation.
Obama pointedly said that Moscow has been cooperative "since the Boston bombings." He made no reference to information being held back ahead of the attack, but he did say, "Old habits die hard. There are still suspicions sometimes between our intelligence and law enforcement agencies that date back 10, 20, 30 years, back to the Cold War."
Russia has also stymied U.S. efforts at the United Nations to mount pressure against Assad's embattled government in Syria.
Assad has refused to let a U.N. team into the areas near Damascus and Aleppo where chemical weapons are believed to have been used. The White House says the team is standing by and could deploy to Syria within 48 hours if Assad allows it in. Given the unlikelihood of Assad giving the inspectors access, the U.S. says it is also seeking answers on its own and through international partners.
