Donald Trump: FactCheck: US has been #1 producer of oil & gas since 2013

THE FACTS: That depends on what the definition of "we" is. His claim is true in the unlikely event he was also crediting Obama and other recent presidents who were aggressive about energy production.

The U.S. now leads the world in oil production, too, under Trump. That's largely because of a boom in production from shale oil, which also began under Obama.

Hatch questioned tax cuts the state gave to a fertilizer plant that located in southeast Iowa, asking "why are we giving these kinds of incentives to corporations, instead of looking where job growth really is, it's in the small towns, it's in the small businesses."

Branstad argued that the deal created jobs for state residents. He also attacked the fiscal policies of the previous Democratic governor, seeking to tie Hatch to a leader that he said didn't balance the books.
