President-elect Trump again took on the matter of the Panama Canal, suggesting to a conference of his supporters that it be returned to U.S. control in a remarkable suggestion to push a sovereign country to cede territory.

President-elect Donald Trump over the weekend suggested the US should retake the Panama Canal, an idea that was immediately rejected by the government of Panama, which has controlled the passage for decades.

The U.S. helped Panama secede from Colombia in 1903 to build the passage that now carries more than 10,000 ships a year.
