Scandals & crimes ledger

resolved — House Ethics Committee Investigation: Outside Earned Income and Business Endorsements (OCE Referral / H. Rept. 115-898)

ethics-violation · 2013-01-01 · U.S. House Committee on Ethics / Office of Congressional Ethics · Committee cleared Mullin of the major allegations (excess $600,000 outside earned income, board service, personal endorsements) citing a good-faith effort to seek guidance. Found that an accounting error led him to inadvertently receive $40,000 in disbursements from Mullin West that he had not been entitled to after transferring ownership; ordered him to repay that $40,000 to the company. No formal reprimand or financial sanction was imposed. Committee voted unanimously to take no further action upon repayment.

The OCE referred Mullin to the House Ethics Committee in December 2013 after he earned more than $600,000 in 2013 from Mullin Plumbing, Inc. and affiliated companies — well above the outside earned income limit then applicable to Members of Congress (~$26,955) — and appeared in radio, TV, and internet ads for the companies while serving on their boards. After a nearly five-year investigation, the Ethics Committee's August 2018 report (H. Rept. 115-898) cleared him of the main allegations, finding he had acted in good faith, but required him to repay $40,000 inadvertently disbursed to him after he had transferred ownership of Mullin West to his spouse. No reprimand was issued.
