It might be the first time - certainly the first time in my lifetime that a major policy address by a Republican presidential nominee Donald Trump so heavily relied on data and studies from a labor-union-backed think tank.

It's far from clear in general that Donald Trump is a guy who really thinks about the details of policy and is going to do the kind of heavy lifting you have to do as president to get those policies through in Congress. I think the hope is that Paul Ryan and his crew will push policies through Congress and Trump will just sign them. That's not really how policy works.

Free trade does bring jobs to America.

[Donald Trump rhetoric]this is a common rhetorical line used by people who are against free trade that say, we're in favor of trade; we just don't like any of the free trade deals that America has actually signed onto.

Donald Trump is now said that he wants to have a plan that's more harmonized with what House Republicans under speaker Paul Ryan have proposed.

This rhetoric that Donald Trump is used is very consistent with rhetoric he's used on the campaign trail for a long time now. He'll always say - and you look - you can look at the past transcripts of his old speeches. He'll always say, I'm in favor of trade; trade is great, but these deals - NAFTA, TPP, the South Korean Free Trade Agreement - are all terrible.

I think he [Donald Trump] recognizes that a plan that would increase the deficit by $10 trillion over a decade is not a plan that's likely to get traction in Congress.
