Fences would be a hindrance to terrorists should they decide to come across a land border between the U.S. and Mexico and to California.

A number of people who have supported me on the border fence in the U.S. have observed the fences in Israel and their effectiveness.

One way to bring down crime in the state of California and every state in the union is to have an enforceable border. That means let's build that border fence. When people want to come into this country, let's ask them to knock on the front door.

Fences work and the walls work and separations work. They afford to any nation the delay of entry.

It takes more than just walking across the border to become an American citizen. It's what's in our souls.

I think in the U.S., the border fence is no longer an immigration issue primarily; it's a security issue.
