The Sept. 22 front-page article “Turnover at the top has DHS unsettled” disregarded the present. In the past nine months, there have been 12 presidential appointments to senior-level positions in the Department of Homeland Security. In fact, 90 percent of all positions at the senior, executive-service level and above across this 240,000-person department are filled.

Besides myself, our new leadership includes Alejandro Mayorkas (deputy secretary), R. Gil Kerlikowske (commissioner of Customs and Border Protection), Suzanne Spaulding (undersecretary for the National Protection and Programs Directorate), John Roth (inspector general), Francis X. Taylor (undersecretary for intelligence and analysis), Reggie Brothers (undersecretary for science and technology), Leon Rodriguez (director for U.S. Citizenship and Immigration Services), Joseph Nimmich (deputy administrator of the Federal Emergency Management Agency), Chip Fulghum (chief financial officer), Brian de Vallance (assistant secretary for legislative affairs) and Tanya Bradsher (assistant secretary for public affairs).

Pending in the Senate are the nominations of Russell Deyo to be undersecretary for management and Sarah Saldana to be assistant secretary for Immigration and Customs Enforcement. With these appointments, virtually every position at the top of this department will have been filled, and they will be occupied by highly qualified public servants dedicated to this nation’s homeland security. Over nine months, this department has quickly transformed into one with steady and able leadership. The Post almost completely overlooked these remarkable, unprecedented changes.
