Partly-printed DS, signed “Sam J. Ervin, Jr.,” one page, 8 x 10.5, October 5, 1973. Congressional subpoena from the Watergate Committee sent to the “Watergate Hotel, 2650 Virginia Ave. N. W., Washington, D.C.,” commanding them to “appear before the Senate Select Committee on Presidential Campaign Activities on Forthwith, Friday, Oct. 5th, 1973…All records relating to the registration of Herbert W. Kalmbach, of Newport Beach, California, for the period from January 1969 to present, including, but not limited to, signature card, transcript of account, telephone calls, use of safety deposit box, and all related documents.” In fine condition, with scattered creases and toning to edges. Kalmbach was Nixon's personal attorney and became embroiled in the Watergate scandal due to his fundraising activities in the early 1970s, some of which supported undercover operatives directed by senior White House figures under Nixon. This included the handling of a $500,000 fund to finance the operations of Donald Segretti, which included sabotage and espionage against Democrats; Kalmbach also raised over $200,000 in 'hush money' to pay off the Watergate burglars. A remarkable document from this historic investigation, especially desirable in that it is directed specifically at the Watergate Hotel. RR Auction COA.
