Trump announced the plan to send a hospital ship just before hosting a dinner for Republican governors at the White House, where he sat next to Landry.
It was unclear what prompted Trump to make the announcement. The White House and the Pentagon haven’t commented on the president’s post. The Danish government and the administration in Greenland also haven’t commented.
Landry reposted Trump’s message in a separate social media post, adding: “Proud to work with you on this important issue!”
The U.S. Navy has two hospital ships, the USNS Mercy and the USNS Comfort, that support troops during deployments and provide services for U.S. disaster relief and humanitarian operations.
Reuters reported that Trump’s post came hours after Denmark’s Joint Arctic Command said it had evacuated a crew member who required urgent medical treatment from a U.S. submarine in Greenland’s waters. It was unclear if Trump’s post had any connection to the evacuation.
