Acting Secretary of Homeland Security Kevin McAleenan is set to testify before the Senate Judiciary Committee on Tuesday about what the Trump administration has deemed a crisis on the U.S.-Mexico border.
The Senate hearing is being held to discuss legislative remedies for the issues at the Southern border.
Republican Sen. Lindsey Graham of South Carolina, who chairs the committee, recently introduced legislation to extend the amount of time children are allowed to be held in U.S. custody to up to 100 days.
The U.S. government is legally not allowed to detain children for more than 20 days, as established by the Flores agreement.
