Ervin’s launch of the Senate Watergate investigation

Sam Ervin’s launch of the Senate Watergate investigation opened a new institutional front in the effort to establish who had financed, authorized, and concealed the political operations surrounding Watergate. The decisive change was not simply that the Senate would investigate: Ervin sought a select committee with sweeping subpoena power, capable of reaching records and witnesses inside the executive branch. In a scandal whose evidence had emerged piecemeal and whose participants were urged to remain silent, the proposed inquiry promised to move the search for answers beyond the boundaries of press reporting and preliminary federal investigations.

From scattered disclosures to a congressional inquiry

Shortly after meeting with Deep Throat, Bob Woodward received a call from the office of Senator Sam Ervin of North Carolina. Ervin, a 76-year-old constitutional scholar and an influential figure on Capitol Hill, wanted to discuss Watergate. On January 11, he had agreed to Senate Majority Leader Mike Mansfield’s request that he preside over a thorough investigation of Watergate and the 1972 presidential campaign. The move promised a broader inquiry than the preliminary work Senator Edward M. Kennedy’s Judiciary Subcommittee on Administrative Practice and Procedure had been conducting since October 1972.

The need for that broader authority was sharpened by what the reporting had already uncovered—and by what remained inaccessible. A cashier’s check for $25,000, payable to Kenneth H. Dahlberg, had been deposited alongside four Mexican checks, producing a total deposit of $114,000; the money was subsequently withdrawn in separate amounts. The Washington Post reported that funds for the espionage operation were controlled by principal assistants to John Mitchell and held in a special account at the Committee for the Re-election of the President. Its account described more than $300,000 earmarked for sensitive political projects, payments to G. Gordon Liddy, destroyed records, and Hugh Sloan’s resignation over suspicions about Watergate. These disclosures pointed toward a financial and organizational story larger than the break-in itself, but did not by themselves establish the full chain of authorization.

The limits of existing inquiries were a central concern. Kennedy had warned that unless a congressional subcommittee quickly used subpoena power to obtain records in areas federal investigators appeared to be overlooking, the chance for a comprehensive investigation might disappear. Woodward told Ervin that the reporters could not identify their sources, that their stories still required checking, and that tracing the secret campaign cash was essential. He described indications of a broad operation associated with H. R. Haldeman, of which the Watergate break-in and dirty tricks during the primaries might be only parts. The reporters, he acknowledged, had only scratched the surface and did not yet understand the full extent of what had happened.

Ervin’s constitutional design

Ervin framed the investigation as an exercise of congressional authority, not merely an inquiry into one burglary. He invoked the separation of powers and argued that the Constitution gave Congress the power to investigate. His plan was to secure a resolution granting a special select committee the broadest possible subpoena authority, then compel the production of documents and the appearance of people wherever necessary—in the executive branch and beyond it.

The proposed reach was deliberately expansive, but it had a stated boundary. Ervin said that anyone mentioned in the published accounts should have an opportunity to appear and clear his name; if a person declined, the committee could subpoena him. When Woodward asked about the prospect of summoning senior White House aides, Ervin confirmed that the investigation could reach them, while drawing a line at the President. Woodward wrote about Ervin’s intention to summon presidential aides and challenge claims of executive privilege. The resulting story made the constitutional contest visible before the committee had even been authorized: Congress would seek evidence from an administration whose senior officials might resist disclosure.

On February 5, Ervin introduced a resolution allocating $500,000 for a Senate Select Committee on Presidential Campaign Activities. Its mandate covered the Watergate break-in and related allegations. The Senate Democratic Policy Committee gave the measure unqualified support, but its passage was not treated as automatic; the remaining danger was a last-minute maneuver by the White House and Republicans. The proposed committee’s authority, funding, and scope had therefore become parts of the political struggle, not just administrative details.

The vote and the attempted redirection

On February 7, Woodward went to Capitol Hill early to watch for a challenge to the resolution. A Republican senator’s aide told him that an amendment would broaden the investigation to include the 1964 and 1968 campaigns. Woodward then called the White House. A source there confirmed that staff members were making calls to senators and that H. R. Haldeman had many of them working on the effort. The proposed expansion could have shifted attention away from the immediate allegations by widening the inquiry across earlier campaigns.

Republican leaders attacked the resolution’s reach. Hugh Scott called its authority exceptionally broad and warned that committee staff could use it for blackmail; John Tower and Barry Goldwater joined the criticism. Scott also alleged wholesale Republican wiretapping in the 1968 campaign, but no specific evidence was offered. The Democrats rejected every amendment proposed by the minority. When the final vote came, Republicans joined Democrats, and the resolution passed unanimously, 77–0. The result did not prove that every senator had embraced the investigation’s aims: veteran Senate reporters told Woodward that Republican support reflected recognition of the Democratic majority’s power. Woodward, however, suspected the senators were reading the political moment as well as the arithmetic. As he left the Capitol, he learned that a Justice Department lawyer sent by the White House had been present to draft the amendments.

Consequences and investigative significance

The resolution established the Senate Select Committee on Presidential Campaign Activities and gave the inquiry a route to seek the evidence Woodward had described: documents, money trails, and testimony extending into the executive branch. Its importance lay partly in the contrast between the breadth of the alleged operation and the narrowness of what investigators could yet prove. Sloan had told the reporters that Mitchell had authorized campaign payments by telephone, initially as the sole person empowered to approve them, and that authority later passed to others, including Jeb Magruder. That account made the question of authorization concrete, while leaving further corroboration and explanation to be established.

Subsequent disclosures showed how consequential that distinction was. Jeb Magruder later told federal prosecutors that John Mitchell and John Dean had approved and helped plan the Watergate bugging operation, and that they later arranged to buy the silence of the convicted conspirators. Separately, James McCord’s testimony connected payoff money to the Committee for the Re-election of the President, giving new weight to earlier suspicions about the secret fund. Deep Throat also told Woodward that L. Patrick Gray had been informed that files concerning the operation were political dynamite and should never become public; Gray said he eventually put them in a burn bag. These later accounts were not the product of the resolution’s vote itself, but they show why the authority Ervin sought mattered: the investigation confronted questions of payment, command, concealment, and the handling of evidence that could not be settled by identifying the burglars alone.

Ervin’s launch thus marked a change in the scale and venue of the Watergate inquiry. A Senate investigation could test the implications of the reporters’ findings against documents and testimony, while directly challenging the idea that executive privilege could shield every presidential aide from scrutiny. The unanimous vote gave that effort formal standing; the unsuccessful amendments and the White House’s intervention exposed the resistance it would face. The investigation began not with a complete account of the conspiracy, but with a public commitment to subpoena the people and records through which such an account might be made.
