"Nothing that has happened in the last 48 hours is surprising to me or many others. Many people were angry and questioned why I would not endorse Donald Trump or attend the Republican Convention. I’ve long had concerns with Donald Trump that go beyond his temperament. We have substantive policy differences on conservative issues like trade, our relationship with Russia, and the importance of balancing the federal budget. I’ve held out hope that he would change on those disqualifying policy positions, but he has not. I’ve also encouraged him to change his behavior for the better and offer a positive, inclusive vision for our country, but he has not. It's clear that he hasn't changed and has no interest in doing so. As a result, Donald Trump is a man I cannot and should not support. The actions of the last day are disgusting, but that’s not why I reached this decision, it has been an accumulation of his words and actions that many have been warning about. I will not vote for a nominee who has behaved in a manner that reflects so poorly on our country. Our country deserves better."
