Union Probe, 02/02/68: A group of Louisiana state legislators arrive in Houston to question witnesses about labor-management racketeering in the Baton Rouge area. In 1967, Louisiana Governor John McKeithen called a special session to address a months-long shutdown of industrial construction in Baton Rouge. With his support, the Louisiana Legislature passed a law to create the Labor-Management Commission of Inquiry to investigate alleged criminal violations in the field. After holding two public hearings in Louisiana, the agency found that witnesses were reluctant to testify, fearing physical harm or economic reprisal. As a result, legislators and commission staff traveled to Houston, where they heard private testimony from a group of witnesses who were once involved in Louisiana construction projects. In May 1968, the Department of Justice launched a probe into the commission and the state attorney general's office to determine if Louisiana was involved in an effort to free union leader and mobster Jimmy Hoffa from federal prison. Harry Roberts, the commission's chief investigator, blamed Teamsters Union Local No. 5 as the main source of labor-management strife in Louisiana. The union's business agent, Edward Grady Partin, was a key witness against Hoffa in his 1964 conviction for jury tampering. Partin alleged that the state investigation was a conspiracy to discredit him and his testimony.
