The Jones Act or Merchant Marine Act of 1920 mandates that all goods shipped between U.S. ports be transported in U.S.-built, U.S.-owned and U.S.-manned ships.
On June 25, 2010, John McCain (R-AZ) introduced legislation to repeal the 1920 maritime law in its entirety. His motion came on day 66 after an explosion on the British Petroleum (BP) Gulf of Mexico oil rig. After this explosion and the months of heavy oil leaking that followed, Hawaii Congress member Charles Djou, R, D-HI, in a letter June 23, joined GOP congress members from Florida and Texas in asking President Barack Obama for a Jones Act exemption in the Gulf of Mexico.
The Jones Act has been revised a number of times and the most recent and thorough revision was the re-codified version of 2006.
