Al Gore appalled by Trump's 'crazy' threats against allies: 'Literally insane'

Former Vice President Al Gore said he was shocked by President Donald Trump's threats against a NATO ally during a speech in Switzerland.

Trump told European leaders in Davos that he would not send troops to seize Greenland from Denmark but still demanded ownership of the world's largest island, saying he would impose severe economic and security penalties if he was not given what he wanted, and Gore reacted to the speech afterwards in an interview with CNN's Kaitlan Collins.
