- Absenteeism among the Miami airport agents has more than doubled since the shutdown began -- meaning there are not enough agents to staff the terminal.
- President Donald Trump is insisting on funding for a wall on the border with Mexico, but opposition Democrats are not budging.
The international airport in Miami has been forced to shut down one of its terminals early for three days due to a shortage of security agents sparked by the partial US government shutdown now in its 21st day.
From Saturday through Monday, Terminal G -- one of six at the airport -- will close at 1:00 pm (1800 GMT).
"Flights that were previously scheduled to depart from Concourse G this Saturday, Sunday and Monday will be relocated either to Concourse F or Concourse H," airport spokesman Greg Chin told AFP.
At issue is a lack of agents from the US Transportation Security Administration, who are seen as "essential" federal workers and hence are still on the job -- but without pay until the shutdown ends.
