If you want to get information about a specific issue from an agency of the U.S. Government, you can file a Freedom of Information Act (FOIA) request. Freedom of Information Act
A basic letter format for a FOIA request follows. This basic format can be used to request information from state agencies also, however, you should know that FOIA does not apply to state agencies. Most states do have some form of open records statutes though. If requesting information from a state agency it would be best to find out what that state's open records laws are and refer to those specific laws rather than FOIA.
It should also be noted that this letter format is typical of that used by an attorney or consultant (note opening paragraph). The format will, however, work for anyone, with minor editing for specifics.
