• Kids are being held beyond the legal time limits in Customs and Border Protection facilities, and the non-profit child shelters overseen by the Department of Health and Human Services are near capacity.
• There are long wait times, sickness and even child deaths.

By the numbers: In fiscal year 2014, during the child migrant crisis under the Obama administration, 68,541 unaccompanied minors were caught crossing the border.

• With 4 months left in the current fiscal year, more than 56,000 unaccompanied minors have already been arrested by border patrol, according to CBP data. Tens of thousands of children also crossed with at least one parent during that time — for a total of more than 230,000 children apprehended for crossing the border.

Here's what happens.

“I have stools and benches, but I have no beds. . . . Our facilities are not built for long-term holding, and they’re certainly not built to house children for very long at all.”

• Homan's latest op-ed published earlier this week on Fox News' site is titled "Trump deserves our thanks for migrant agreement with Mexico."
• After Trump threatened to send immigrants who crossed the border illegally to sanctuary cities, Homan called it an "ingenious" idea on Fox.
• Last year, as thousands of migrant children were separated from their parents under the "zero-tolerance" policy, Homan he defended the policy.

Go deeper: Most unauthorized immigrants in the U.S. are not Mexican

Mexicans no longer make up the majority of unauthorized immigrants in the U.S. — a significant change from the early 2000s — as more are leaving than arriving, according to a new study by the Pew Research Center.

The big picture: The immigrant population in the U.S., which has its smallest unauthorized immigrant population in more than a decade, is markedly shifting.

• There are fewer new unauthorized immigrants now. The majority — 66% — have been in the U.S. for at least a decade. In 2000, unauthorized immigrants were more likely to have been in the U.S. for fewer than 5 years than over 10.

Between the lines: The change isn't because border enforcement has improved. Mexicans simply aren't attempting to cross the border as often as they used to. In 2000, 98% of all border patrol arrests were of Mexican nationals. Last year, Mexicans made up just 38% of border arrests, according to Customs and Border Patrol data.

• Meanwhile, there's been a surge of migrants from Central American countries, like Guatemala, El Salvador and Honduras.
• And the share of both legal and unauthorized immigrants from Asian nations has continued to grow.
