CBO Releases a Report on the Proposed Homeland Security Budget for 2013
from CBO Recent CBO Publications
Since the terrorist attacks of September 11, 2001, the federal government has spent more than half a trillion dollars on homeland security—that is, activities that detect, deter, protect against, and respond to terrorist acts occurring within the United States and its territories. Those activities are carried out by numerous federal agencies and include many, but not all, of the responsibilities of the Department of Homeland Security (DHS). In fact, only about half of the $69 billion in funding for homeland security in the President’s budget for 2013 would be allocated to DHS.
