The administration will hold a 6 p.m. call Thursday to brief Congressional leadership and relevant committee leaders on Syria, multiple sources confirmed.
The call, which will be led jointly by officials from the State and Defense Departments as well as intelligence agencies, will review unclassified information about the reported use of chemical weapons on the Syrian people.
The administration has made it clear that it believes the intelligence that the Syrian regime controlled and executed strikes from its chemical weapons stockpiles is convincing. But there is some question on the strength of the intelligence linking Syrian leader Bashar al-Assad to the reported strikes, according to an Associated Press story published Thursday.
Sources on the Hill said they believed Secretary of State John Kerry and National Security Adviser Susan E. Rice would be on the call, but administration officials could not immediately verify their participation.
