The White House has reportedly asked Congress for $4.5 billion in emergency spending for the U.S.-Mexico border.
The request cited the growing "humanitarian and security crisis" at the border. It includes $3.3 billion for humanitarian aid to help house migrants and $1.1 billion for border operations.
This is on top of the $6 billion President Donald Trump asked for in his national emergency declaration in February, the $1 billion the Pentagon approved in March to start building a barrier along the border, and the $8 billion President Trump asked for in his most recent budget request.
The acting budget director wrote in the request that the Department of Health and Human Services is running out of money to help support child welfare services at the border. If that happens, HHS might have to "divert significant resources from other programs."
