When I talked to [Donald Trump] about - our intelligence agencies, what I've said to him is - is that there are gonna be times where you've got raw intelligence that comes in and in my experience, over eight years, the intelligence community is pretty good about saying, "Look, we can't say for certain what this means." But there are gonna be times where the only way you can make a good decision is if you have confidence that the process is working, and the people that you put in charge are giving you their very best assessments.

I mean, if you think about - if you think about it, UPS and FedEx are doing just fine, right? No, they are. It's the Post Office that's always having problems.

Of course, there's been a real debate about where to invest and where to cut, and I'm committed to working with members of both parties to cut our deficits and debt. But we can't simply cut our way to prosperity.

A lot of countries have advanced capabilities. And given the vulnerabilities of our infrastructure and our economies to digital platforms, we have to be careful in making sure that this doesn't become a lawless, low-level battlefield.

Keeping the people's government open is not a concession to me. Keeping vital service running and hundreds of thousands of Americans on the job is not something you 'give' to the other side.
