Many Members of Congress getting Classified Meeting regarding Syria now

I'm watching CNN with Dana Bash who is videoing members of Congress in Casual clothes on this Labor Day Holiday Weekend steaming into a Classified briefing room for information regarding their upcoming vote on Syria. Senator McCain is to meet with the President at the White House on Monday.  This is a legacy full court press for the Obama adminstration to get the vote for action in Syria soon (within the next month or so).
