U.S. Sen. Mark Warner (D-Va.) stated on X that U.S. allies are sending troops to Greenland, questioning the Trump administration's actions, in a post between 6:17 p.m. and 6:46 p.m. UTC on January 18, 2026. National Economic Council Director Kevin Hassett called for cooler heads amid EU sanction threats over U.S. tariffs. Warner posted: "Our closest allies are sending troops to Greenland. What the hell is this administration doing?" according to his X account. The claim emerged in the 29-minute period ending at 6:46 p.m. UTC. Hassett urged de-escalation, stating: "When you are engaged in negotiation with any country and with President Trump, that you'll see both sides take very strong extreme positions. But in the end, the president is the person who wrote 'The Art of the Deal' because he's so good at deal making. And so I think right now it's really a good time for cooler heads to prevail and for us to disregard the rhetoric and get to the table and see if there can't be a deal that's worked out that's best for everybody," according to an X post by Jacqui Heinrich. Hassett's remarks addressed threats by EU parliament members to sanction "Trump's oligarchs" over new tariffs. These developments follow NATO Secretary General Mark Rutte's call with President Donald Trump on Greenland and Arctic security earlier today, as stated by @SecGenNATO.
