Internal Revenue Service officials in Washington and at least two other offices were involved with investigating conservative groups seeking tax-exempt status, making clear that the effort reached well beyond the branch in Cincinnati that was initially blamed, according to documents obtained by The Washington Post.
IRS officials at the agencys Washington headquarters sent queries to conservative groups asking about their donors and other aspects of their operations, while officials in the El Monte and Laguna Niguel offices in California sent similar questionnaires to tea-party-affiliated groups, the documents show.
