US Senator John McCain has again introduced legislation aimed at rolling back the US-build requirement of the Jones Act.

The lawmaker, a one-time Republican presidential candidate who has long opposed the US cabotage law, dubbed his bill the Open America's Waters Act.

He calls the Jones Act, which requires US-built, US-owned and US-crewed vessels for domestic trades, an "archaic and burdensome law that hinders free trade, stifles the economy, and ultimately harms consumers".
