Once again the Washington Post has addressed some of the organizations concerns and the severe deficiencies of the Congressional oversight of  DHS.  See: Department of Homeland Security has 120 reasons to want streamlined oversight. From the lead in to the article:

The Department of Homeland Security is, by all accounts, not the easiest place to work. The pressure is high, the job is hard and morale in recent years has been about as low as it can get.

But perhaps the most universally frustrating part of working for DHS, according to numerous former and current officials, is the byzantine congressional oversight.

More than 90 committees and subcommittees have some jurisdiction over DHS, nearly three times the number that oversee the Defense Department. And that doesn’t count nearly 30 other congressional bodies such as task forces and commissions.
