Donald Trump Jr is planning to visit Greenland, two weeks after his father repeated his desire for the US to take control of the island - an autonomous Danish territory.

The US president-elect's son plans to record video footage for a podcast during the one-day private visit, US media report.

Donald Trump reignited controversy in December when he said "ownership and control of Greenland is an absolute necessity" for US national security.

He had previously expressed an interest in buying the Arctic territory during his first term as president. Trump was rebuffed by Greenland's leaders on both occasions.
