Hillary Clinton's position on policy on markets and trade is very plain, which is we'll do trade deals but only if they meet three criteria, increase American jobs and wages and are they good for national security. If they are and if we can enforce them, then trade deals are okay. If not, we can't embrace them.

Donald Trump proposes to deport 16 million people, 11 million who are here without documents. And both Donald Trump and Mike Pence want to get rid of birthright citizenship.
