"Though consulting with Congress is helpful, it is in no way an adequate substitute for President Obama obtaining statutory authority from Congress prior to the use of military force, as required by the Constitution," Rigell said.

Earlier this week, Rigell spearheaded a letter to President Obama, which was signed by more than 100 members of the House, demanding congressional approval of military action in Syria.

Senior administration officials have spoken with congressional leaders throughout the week on Syria and are expected to brief members again later today.
