Biden and his wife, Dr. Jill Biden, were scheduled to host the senators for dinner as part of the White House's effort to win support for military action in Syria.
The president spent approximately an hour and 20 minutes with Biden and the senators.

The Hill's latest whip list counts nine Senate Republicans as "yes/leaning yes" while 14 GOP senators are listed as "no/leaning no."
Ayotte, Chambliss, Corker and Graham are listed as "yes/leaning yes." Collins and Fischer are among 23 Senate Republicans listed as "undecided."

McDonough brushed aside the rising number of voices in Congress against military action, saying it was still “too early” to reach conclusions.

Obama will also conduct interviews with six television networks ahead of a primetime speech on Syria Tuesday night in an effort to win over lawmakers and the public.
