Homeland Security Secretary Kirstjen Nielsen requested that DHS employees volunteer to assist Customs and Border Patrol and ICE "in responding to the emergency at the southern border" in a letter on Wednesday, obtained by CNN.

What's happening: In the letter, Nielsen also called for interagency assistance as the DHS reportedly diverts resources away from border security and "toward full-time humanitarian response." What's included in that humanitarian response: Nielsen is expected to ask Congress in the coming days for permission to deport unaccompanied migrant children and hold families seeking asylum in detention longer than currently permitted, as outlined in a March 28 letter obtained by NBC News.

  • "My greatest concern is for the children ... who are arriving sicker than ever before," the March 28 letter reads. Nielsen says she has met with "senior Mexican officials" to discuss how to "stem the historic flows" from both sides of the border.

Why it matters: This will have a snowball effect on the rest of the country, and could force all Power 5 conferences to follow suit, resulting in a regionalized fall sports season.

The second jobs apocalypse

This week, United Airlines warned 36,000 U.S. employees their jobs were at risk, Walgreens cut more than 4,000 jobs, Wells Fargo announced it was preparing thousands of terminations this year, and Levi's axed 700 jobs due to falling sales.

Why it matters: We have entered round two of the jobs apocalypse. Those announcements followed similar ones from the Hilton, Hyatt, Marriott and Choice hotels, which all have announced thousands of job cuts, and the bankruptcies of more major U.S. companies like 24 Hour Fitness, Brooks Brothers and Chuck E. Cheese in recent days.
