Immunity for witnesses testifying before congressional committees

When a witness before a congressional committee asserts his fifth amendment privilege against self-incrimination, the committee may obtain a court order which compels him to testify and grants him immunity against the use of his testimony and information derived from that testimony in a subsequent criminal prosecution. He may still be prosecuted on the basis of other evidence.,Jay R. Shampansky, Legislative Attorney, American Law Division,CRS 86-1026 A,"December 10, 1986.",SuDoc# 14. 18/3
