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.

The United States compared to a number of our competitors is the only government in the world with any kind of safeguards, any kind of checks and balances. They may in many respects need to be strengthened and people need to be reassured, and they need to have their protections embodied in law.

If [Donald Trump] is paid zero [taxes], that means zero for troops, zero for vets, zero for schools or health.

You've got to ask yourself, why won't Donald Trump release his tax returns? I think there may be a couple of reasons. First, maybe he's not as rich as he says he is. Second, maybe he's not as charitable as he claims to be. Third, we don't know all of his business dealings, but we have been told through investigative reporting that he owes about $650 million to Wall Street and foreign banks. Or maybe he doesn't want the American people to know that he's paid nothing in federal taxes.

I've heard [Bernie] Sanders comments, and it's really caused me to wonder who's left in the progressive wing of the Democratic Party. Under his definition, [Barack] Obama is not progressive because he took donations from Wall Street; [Joe] Biden is not progressive because she supported Keystone; [Jeanne] Shaheen is not progressive because she supports the trade pact. Even the late, great Paul Wellstone would not fit this definition because he voted for DOMA.

I've never understood the division between so-called realists and so-called idealists.
