I think we've made the collection haystack so big, no one's ever getting through the haystack to find the needle. What we really need to do is isolate the haystack into a group of suspicious people and spend enormous resources looking at suspicious people, people who we have probable cause.

You have to decide in advance whether you're ready go to war. If you guys are ready to send a million troops into Ukraine and fight World War III, you're going to do it without my support because I think that's a really foolish notion.

For liberty to expand, government must shrink. For the economy to grow, government must get out of the way.

I think that there is a bipartisan consensus that's incorrect that we should have the whole world be in NATO. For example, if we had Ukraine and Georgia in NATO - and this is something McCain and the other neocons have advocated for - we would be at war now because Russia has invaded both of them.

I think we're never fully protected, but I think we need to do everything we can to stop threats to us.

Just because a couple people on the Supreme Court declare something to be 'constitutional' does not make it so.

You can be strong without being involved in every single civil war around the world.
