"This dangerous conflict threatens American national security interests in the region, and I wanted to take this opportunity… to urge members to attend the classified briefing that the administration will be providing tomorrow morning at 9:30 a.m. in the CVC auditorium," Cantor added.

Syria has been in a state of civil war since 2011, as opposition forces seek the ouster of President Bashar al-Assad's regime. Assad has responded by using military force against these opponents, often with civilian casualties.

Cantor's comments come after the White House acknowledged on Thursday it believes Assad used chemical weapons. The administration said they hoped to "build" on intelligence assessments, suggesting they have not yet planned to take military action.
