As thousands of migrant parents and children continue to stream across the U.S.-Mexico border every day, the Border Patrol is bringing in more agents and asking the Pentagon for additional help.

The Border Patrol says it needs more manpower to care for the migrants — more of whom are coming with infectious diseases. Homeland Security Secretary Kirstjen Nielsen says agents are on track to stop nearly 100,000 people crossing illegally this month — far exceeding last month's total.

The Trump administration is again turning to the Defense Department, and plans to request more active-duty troops to help with migrant processing, transportation, and medical care in high-crossing areas, according to an official with Customs and Border Protection, or CBP.
