Teamsters president Sean O’Brien took a victory lap on social media after calling Sen Markwayne Mullin of Oklahoma a “greedy CEO” at a contentious Senate hearing on Wednesday.
Mr O’Brien, a Boston native who defeated an incumbent to be elected president of the International Brotherhood of Teamsters in 2021, was in Washington, DC on Wednesday to testify before the Senate committee on Health, Education, Labor and Pensions (HELP).
