Task: Question Generation
Input (English): Passage: Prior to the signing of the bill, controversy about its adoption centered on whether the Federal Bureau of Investigation and the Central Intelligence Agency should be incorporated in part or in whole . The bill was also controversial for the presence of unrelated "riders", as well as for eliminating certain union-friendly civil service and labor protections for department employees. Without these protections, employees could be expeditiously reassigned or dismissed on grounds of security, incompetence or insubordination, and DHS would not be required to notify their union representatives. The plan stripped 180,000 government employees of their union rights. In 2002, Bush officials argued that the September 11 attacks made the proposed elimination of employee protections imperative. Congress ultimately passed the Homeland Security Act of 2002 without the union-friendly measures, and President Bush signed the bill into law on November 25, 2002. It was the largest U.S. government reorganization in the 50 years since the United States Department of Defense was created. Tom Ridge was named secretary on January 24, 2003 and began naming his chief deputies. DHS officially began operations on January 24, 2003, but most of the department's component agencies were not transferred into the new Department until March 1.
Output (English): How many days after President Bush signed the Homeland Security Act did DHS officially begin operations?
