We weren't able to obtain the necessary security clearance from the Department of Homeland Security.

The flight was canceled because we were unable to obtain the necessary security clearances from the Department of Homeland Security and their international counterparts.

I have a feeling that makes me very uneasy that the Department of Homeland Security is dysfunctional,

The Homeland Security department doesn't have tasking authority in the intelligence community. They can ask for stuff, but they can't direct anything except inside their bureau.

Michael Chertoff and the Department of Homeland Security, they have the primary responsibility of ensuring that our ports are secure.

They came completely prepared to answer all of our questions. They will be able to obtain the necessary financing to complete the project.
