The top Democrat and Republican on the House Homeland Security Committee are deriding as “unacceptable” a failure from the secretary of Homeland Security to respond to a subpoena from the panel for last week.

The documents in question relate to the Department of Homeland Security (DHS) role in enforcing border security and immigration laws.

"You are required to produce the responsive documents, which are essential to the Committee’s oversight of the Department’s border security activities, including the treatment of children in custody, the separation of families, and metering of individuals at ports of entry," wrote Thompson and Rogers.

DHS representatives did not immediately respond to a request for comment.

The subpoena was issued by the committee on Nov. 20 and approved in a bipartisan voice vote.

In his letter from the time issuing the subpoena, Thompson noted DHS "has not been responsive to our requests for documents related to the handling of children, families and others who were apprehended at the southwest border by U.S. Border Patrol or who had sought to access a port of entry maintained by [Customs and Border Protection] Office of Field Operations to make asylum claims."
