Republican Senator Markwayne Mullin had a heated argument with the head of a union on Wednesday.
Mullin claimed he only paid himself a $50,000 salary and "invested every penny" into his business.
While lambasting Teamsters president Sean O'Brien for his nearly $200,000 salary, Oklahoma's Senator Markwayne Mullin claimed that he paid himself a salary of just $50,000 when he ran a plumbing business.
I kept my salary down at about $50,000 a year because I invested every penny into it," Mullin replied.
He reported between $200,000 and $2 million in income in 2012 from two family companies, Mullin Plumbing Inc. and Mullin Plumbing West, and another $15,000 to $50,000 from shares he held in a bank.
