President Donald Trump's special envoy to Greenland was heckled in Greenland's capital, according to video on social media. Louisiana Governor Jeff Landry, arrived in Nuuk for the first time on Sunday in a bid to calm tensions after Trump threatened to annex the Arctic country for U.S. national security reasons. Greenland's Prime Minister Jens-Frederik Neilson said on Monday that he had a respectful and positive meeting with Landry, but that he made it clear that the Greenlandic people continue to insist on self-determination. "The Greenlandic people are not for sale. Greenlandic self-determination is not something that can be negotiated," Nielsen was quoted by Danish TV 2 as saying after meeting with Landry.
