President Trump on Friday wrote in a tweet that he’ll make “a major announcement” Saturday afternoon concerning the ongoing partial government shutdown and the “humanitarian crisis” on the southern border.

But despite a recent surge in asylum-seeking families from Central America in recent months, the data indicated that border arrests remain low by historical standards.

The Border Patrol made 396,579 arrests on the Mexican border in the 2018 fiscal year, up 30 percent from a 46-year low during the same period a year earlier but still well below a high of more than 1.6 million in 2000.
