The real number of the US' obligations, unfunded obligations that we're passing on to our future generates is more like $70 trillion to $75 trillion. The vast majority of that is health entitlements - Medicare, Obamacare, Medicaid. There's also Social Security, interest on the debt. But fundamentally, health entitlements are the thing that will bankrupt our kids. We need to fix that for the long-term.

I don't understand what the president's [Donald Trump] position is on Russia. But I can tell you what my position is on Russia: Russia is a great danger to a lot of its neighbors, and [Vladimir] Putin has as one of his core objectives fracturing NATO, which is one of the greatest military alliances in the history of the world.

In the American constitutional system of three different branches, conflict - and I mean that peaceful, vigorous debate - it's a feature of our system, not a bug. We need less all-or - winner-take-all politics.

Let's be clear: Has the U.S. ever made any mistakes? Of course.Is the U.S. at all like [Vladimir] Putin's regime? Not at all.

The U.S. affirms freedom of speech.[Vladimir] Putin is no friend of freedom of speech.

There is no equivalency between the United States of America, the greatest freedom loving nation in the history of the world, and the murderous thugs that are in [Vladimir] Putin's defense of his cronyism. There's no moral equivalency there.

I think I'm one of five people in the Senate who's never been a politician before. And now that I am a politician, what I find weird about it is that I respect myself less.
