Troubling revelations and a historically poor track record at the Department of Homeland Security means that the Homeland Security Committee must conduct aggressive oversight and hold the Department's leadership responsible for its problems. If we don't hold the DHS leadership to account for their failures, it will look like the Department is just doing bad business as usual. I hope that we can hear directly from Secretary Chertoff and Deputy Secretary Jackson in the weeks to come on these and other issues of concern at DHS.Our Committee must conduct aggressive oversight and hold Department leaders accountable for the waste, fraud, and abuse fiascos that permeate throughout the agency. We should do this before Congress recesses for a whole week for the 4th of July. America's security cannot wait.
