US and China edging closer to trade deal

Donald Trump says the US is edging closer to a trade agreement with China and an "epic deal" could come in the next four weeks.

Correspondent Harry Horton says one of the major sticking points in negotiations is how fast to roll back existing tariffs, and how to enforce any agreement.
