Trump wrote on Truth Social that if Democrats did not immediately sign a funding agreement, "I will move our brilliant and patriotic ICE Agents to the Airports where they will do Security like no one has ever seen before."
A couple of hours later, he posted that "I look forward to moving ICE in on Monday, and have already told them to, 'GET READY.'"
The posts came hours after tech tycoon Elon Musk offered to cover the salaries of US airport security personnel who have been working without pay since mid-February because of the partial government shutdown.
