From The Hill:

The Department of Homeland Security (DHS) has faced significant challenges since its inception 10 years ago. As the third largest federal agency, the DHS is responsible for preventing terrorism, protecting our cyberspace, protecting our borders and many other mission areas. Yet, after 10 years, the department still faces substantial issues that require rigorous congressional oversight. The House Homeland Security subcommittee on oversight and management efficiency that I chair has taken numerous actions to keep the department accountable to the American taxpayer.
