You know, everybody has setbacks in their life, and everybody falls short of whatever goals they might set for themselves. That's part of living and coming to terms with who you are as a person.

We are Americans, We have the right to participate and debate any administration.

We've got to get guns out of the hands of people who should not have them.

We know that Donald Trump has shown a very troubling willingness to back up [Vladimir] Putin, to support Putin, whether it's saying that NATO wouldn't come to the rescue of allies if they were invaded, talking about removing sanctions from Russian officials after they were imposed by the United States and Europe together, because of Russia's aggressiveness in Crimea and Ukraine, his praise for Putin which is I think quite remarkable.

We have to work to make sure that our police are using the best training, the best techniques, that they're well prepared to use force only when necessary.
