From the Phoenix Business Journal:

U.S. Sen. John McCain, R-Ariz., has introduced legislation to undo a ‘Buy American’ law that dates back to 1920.

McCain wants Congress to repeal the decades-old Jones Act. The law institutes some rules and regulations on shipping.

That includes regulations on waterborne shipping between two U.S. locations that dictate the ships used for that cabotage must be done on ships built in the U.S. Those ships must also be owned by American companies.

It prohibits foreign-owned or foreign-flagged ships from engaging in inter-coastal trade within the U.S, according to the Maritime Law Center.

McCain wants those rules to go away and has pushed for the repeal of the Jones Act — which also is known as the Merchant Marine Act of 1920.

McCain is a big backer of free trade deals including the North American Free Trade Agreement which Trump is reworking.
