morning. he said the speech isn't intended to divide congress but it really looks like that's exactly what it's doing. >> reporter: of course. because at its heart, it is coming from a place of division because the invitation came from the house speaker, who only did so because he wants benjamin netanyahu to get out to the american people and the world why he believes the nuclear deal that the white house is working on with its allies to deal with iran is just flat wrong. so that's why you will have maybe even more than the 30 plus that will be boycotting and a lot of those who will be going are going to be going and just sitting there politely because they want to show respect, but not because they think it's a good thing to do. listen for the prime minister to try very hard to pressure members of congress to use their power, their legislative power, to try to stop any kind of deal that comes out of switzerland. >> so if you hear dozens of republicans aren't going, who do we expect to fill the seats that will be empty from them?
