I have a treasure trove of Baker memories, all of which reinforce my sense of Howard Baker as one of the most decent people with whom I have worked. While I was simply a young staffer, he never treated me or my colleagues as anything else but equals.

He [Donald Trump]wants to build the wall. It would be silly to say we`re going to - we`re going to create an army and we`re going to have Mexico pay for our border patrol, our border police. Clearly, that`s not going to happen.

I was part of the gang of eight in the house in 2013 that was working on comprehensive immigration reform. We talked a lot about border security and what was effective and what was not. Walls are not effective when you`re out in the desert and you don`t need them.
