During a historic gathering in Saudi Arabia, I called on the leaders of more than 50 Muslim nations to join together to drive out the menace which threatens all of humanity. We must stand united against shared enemies to strip them of their territory and their funding, and their networks, and any form of ideological support that they may have. While we will always welcome new citizens who share our values and love our people, our borders will always be closed to terrorism and extremism of any kind.

President [Barack] Obama and Hillary Clinton support sanctuary cities. They support catch and release on the border, they support visa overstays. They support the release of dangerous, dangerous, dangerous, criminals from detention. And, they support unconstitutional executive amnesty.

Will I get along with [Vladimir Putin]? I have no idea.

You see the crowds. I mean, you don't see enthusiasm like that at a Hillary [Clinton] rally. People are falling asleep.

I do know this: other countries are eating our lunch.

I've ordered plans to begin for the massive rebuilding of the United States military. Had great support from the Senate. I've had great support from congress, generally. We've pursued this rebuilding in the hopes that we will never have to use this military.

We have been there for 15 years in the Middle East, and much more than that probably. And we have spent probably $4 trillion, maybe more than that. And it's time to do something about it. And it's time to also knock ISIS out. You got to knock ISIS out.
