To mark the 40th anniversary of the Watergate break-in on June 17th, the Richard Nixon Presidential Library released interviews with key staff charged with investigating whether there were grounds to impeach President Nixon. This is the first time that many of these individuals have spoken for the record about the work and inner politics of the impeachment inquiry. A selection of these interviews will be televised for the first time on American History TV throughout June. This is an oral history from William Weld, who served as a member of the House Judiciary Committee impeachment staff. He recalls the committee’s work to define what constituted grounds for impeachment. Mr. Weld later served as governor of Massachusetts.
