DHS chief Mick Mulvaney told House Democrats Tuesday that the agency has a unified command on “emergency” cases.

The White House has been trying to push the case of a man with a history of mental illness who was shot dead by an agent who tried to take his gun after a domestic violence incident to a higher level of management.

“The top leadership has asked us to do this,” Mulvane told the House Appropriations Committee.

“We are going to do it.”

He went on to call for a “bipartisan” approach to emergency cases.

Mulvane said the Department of Homeland Security would be “very much in” the loop with any agency request for additional resources, including extra resources for the FBI.

Militant Islamist gunman Omar Mateen opened fire at a gay nightclub in Orlando, Florida, killing 49 people and injuring 53 others on June 12.
