WASHINGTON (AP) — U.S. officials say active duty troops will begin leaving the southern U.S border this week and the number of forces there will go down to at least 3,000 by the holidays.

There have been roughly 5,400 active duty troops along the Mexican border in recent weeks installing wire barriers and protecting border patrol agents in Texas, California and Arizona.

President Donald Trump ordered the deployment of troops in response to a caravan of Central American migrants moving toward the U.S. border. The number of migrants has been declining and the military has finished much of the wire barrier placement.

Officials say there is less need for combat engineers and helicopter transport crews. But many of the military police will remain. The officials spoke anonymously because they weren’t authorized to speak publicly.
