The chair of the House Oversight Committee, Carolyn B. Maloney, announced Tuesday that she would be investigating claims that Postmaster General Louis DeJoy violated campaign finance laws.

The announcement by Rep. Maloney came after a report by the Washington Post over the weekend alleged that, while DeJoy was the CEO of New Breed Logistics in North Carolina, he encouraged employees to donate to Republican candidates. It is further alleged that he gave those employees larger than normal bonuses as a way to reimburse them for the donations. An employer’s request that employees donate is not improper as long as employees felt no pressure to donate and were not subject to sanction if they did not donate. However, reimbursing employees for their donations is a violation of campaign finance law, as it is a way to circumvent campaign contribution limits.

Rep. Maloney noted that if the allegations were true, “Mr. DeJoy could face criminal exposure—not only for his actions in North Carolina, but also for lying to our Committee under oath.” The latter part of her statement refers to DeJoy’s testimony before the Oversight Committee last month, in which he denied reimbursing employees for campaign contributions. DeJoy is facing a subpoena from the committee for documents related to contradictory statements he gave during that hearing about whether or not he had been in contact with members of the Trump campaign regarding controversial policy changes that have resulted in a slowdown of mail service and have called into question the ability to vote by mail in November.

When asked if the Postmaster General should lose his job if the allegations are proven to be true, President Trump said, “Yes, if something can be proven that he did something wrong, always.”
