The new Republican chairman of the House oversight committee is demanding details of every request for federal records made by citizens, journalists, companies and others during the last five years under the Freedom of Information Act. The chairman, Representative Darrell Issa of California, said the committee wants to make sure that “all federal agencies respond in a timely, substantive and non-discriminatory manner” to requests for records under the information law. The request went to 180 federal offices, including the Departments of Defense, Education, Justice, Commerce, State and Transportation, along with the Central Intelligence Agency, Environmental Protection Agency and NASA. Some federal agencies receive tens of thousands of information requests each year. The Defense Department last year received 73,572 such requests, and the Justice Department received 63,682.
