An investigation by the Federal Bureau of Investigation has now called into question the private lives and careers of two of the nation’s top national-security officials. Here is an accounting of what is known so far.
The White House has released 100 pages of e-mails related to its handling of the terrorist attack on a US diplomatic facility in Benghazi, Libya. They present a fuller picture of a chaotic situation, but are unlikely to quiet critics questioning the administration's 'talking points' at the time.
Israeli air strikes on Damascus and the conflicting reports on the use of chemical weapons (sarin gas) may complicate President Obama's decision on intervention in Syria. The US must consider the international laws of war before taking any action.
Shane Todd, a US citizen working in Singapore, believed he had access to restricted tech. His death in 2012 was by suicide, say local authorities. But his family, suspecting murder, wants the FBI to take part in the investigation.
The federal government is now examining the intelligence it had of Tamerlan Tsarnaev prior to the Boston marathon bombing in order to determine whether it could have acted to prevent the attack. Different spellings of the suspected bomber's name appear to have helped him avoid detection during recent travels to Russia.
