Donald Trump s proposal to build a wall between the United States and Mexico is absolutely ridiculous. It s unnecessary, counter-productive, and an insult to our national neighbor. The fact that Trump thinks that Mexico should foot the bill for the mega-project serves as the cherry on top of the giant pile of bullsh*t that Trump has served to his supporters insisting that it is made of ice cream.The proposal is just one of many elephants in the room that the GOP is refusing to give any coherent opinion on. That s why when Republican Senator Bob Corker appeared on ABC s This Week, the show s host George Stephanopoulos pressed the Senator for some clarity on the matter.Here s a transcript of the exchange:GEORGE STEPHANOPOULOS: Senator, let me go ahead, let s talk about his ideas. You are the chair of the Senate Foreign Relations Committee and you ve said his call for a temporary ban on Muslim immigration is not a serious proposal. The former head of the CIA Michael Hayden said this morning it s a recruiting tool for ISIS. If Donald Trump as president, moved to impose that ban would you support it or try to stop it?SEN. BOB CORKER No, I would not support it and I ve already issued statements to that effect and what I understand is he has stepped away from those statements.STEPHANOPOULOS: Well, he has said he still supports those statements. He s also said in every speech that he talks about building a wall on our border and getting Mexico to pay for it. Is that realistic and what would it do to our relations with Mexico?CORKER: You know, obviously we do need to have good relations with Mexico and Canada. We do. That s one of the things that makes our country in such a stable environment having two friends on our borders unlike many countries around the world. There is a security issue. I authored an amendment during the immigration debate that actually makes building a wall look like Ned in the first reader meaning it was even more difficult and by the way, I mean, a tougher security border measure   by the way, every Democrat in the Senate voted for that measure. So there s no question that we have agreement in our country that we need greater security. It s strongly bipartisan and I hope that we will implement that because it is a security threat.STEPHANOPOULOS: But is it realistic to expect Mexico to pay for the wall?CORKER: Again, I think people agree with that   what s that?STEPHANOPOULOS: Is it realistic for people to expect Mexico to pay for that wall?CORKER: Well, again, I don t want to get into a debate about the nuances of that. I mean it s a statement that he has made. I thought this interview was going to be more about the foreign policy arena. I think he has a tremendous opportunity there.STEPHANOPOULOS: Well, our relations with Mexico is foreign policy.CORKER: Okay. Well, look, as to how the wall is paid for, that s something that Congress certainly will debate. My guess is there will be additional debates regarding how the actual security measures will be put in place but securing our border has been something that people on both sides of the aisle have supported for years and we need to do that and it s understandable that it s become an issue because it s lingered for so long. We had an opportunity to deal with this years ago. It wasn t dealt with. Needs to be dealt with now. And hopefully we ll move beyond that very quickly.Surprise, surprise. No clear answers on one of the most important topics of the election cycle. If you can t answer a simple question about what may become part of your party s platform   it might be a good sign that it is time to jump off the ship.These days, it s looking more and more like top members of the Republican Party are embarrassed to be a member of that party. The Republican National Convention is coming up fast, sooner or later the GOP is going to have to decide if they are willing to go completely off the deep end and agree to support Trump s fascist proposals.You can watch the interview below.
