Trump slams Danish PM's 'nasty' rejection of Greenland deal

US President Donald Trump snapped back Wednesday at Denmark's premier in a row over his desire to buy Greenland, saying her blunt refusal to consider any negotiation was "nasty."

Speaking after he scrapped plans to visit Copenhagen next month, Trump told reporters he had taken offence at Danish Prime Minister Mette Frederiksen's description of any such deal as "absurd."

"She's not talking to me, she's talking to the United States of America.
