From the April 10 edition of Fox Business' Lou Dobbs Tonight:
LOU DOBBS (HOST): This surge though looks as though it is going to continue.
A friend of mine sent me pictures from Guatemala, of another caravan being formed there. It looks like there is every intent -- we know that behind all of this is a lot of left wing money, a lot of groups that are working with amongst others the United Nations for crying out loud in Central America.
This is going to be difficult to stop unless, as the president says, Mexico stops it.
