listen to what marco rubio said just this morning. >> i listened to the interview earlier today. i guess secretary tillerson is going to have on your program and i'm a bit concerned about the outlines of the strategy as i understand it. i think it is based on assumptions that, quite frankly, are not the right ones. i hope they will reconsider. this idea we will get rid of isis and then we'll hopefully use assad and others to come up with a solution, it is not going to work. these people who have been killed and gassed and human rights violations against them will never accept assad as a rightful ruler. >> let's bring in my panel. with me cnn political analyst and columnist for "the washington post" josh rogin and white house correspondent for the washington examiner sarah westwood. the white house may have to get approval from congress before taking action serious. rubio is voicing concerns. could that be problematic? >> absolutely. there are already democrats who are concerned about getting more militarily involved in syria.
