President Donald Trump's push to acquire Greenland has sparked a backlash from Republicans in Congress, as lawmakers voice growing concern about US military interventions overseas.
But it remains unclear if enough Republicans are willing to join Democrats to block a takeover of the island territory - and whether Trump would bow to pressure from Congress, or act alone as he's done several times in a second term marked by growing American entanglements abroad.
The focus on Greenland has grown into a broader discussion over the Trump administration's unilateral use of military force, along with diplomatic and economic coercion, to project power in Venezuela, Iran and elsewhere around the world.
Republicans have largely backed Trump's foreign policy agenda since he returned to the White House. But now, a growing number are siding with Democrats in Congress and NATO allies who say a takeover of Greenland would violate US and international law.
In recent days, some Republican leaders have expressed little interest in the US buying Greenland or seizing it through military force. The White House had previously left the military option open, but Trump ruled it out during a speech at the World Economic Forum in Davos.
Some Republican lawmakers have also joined Democrats in opposing Trump's new tariffs on countries that don't support his Greenland bid, citing concerns that such tariffs would hurt US businesses and allies.
As Trump continues to assert the necessity of controlling Greenland for national security, the sentiments in Congress indicate increasing bipartisan apprehension, posing potential limits on his plans.
