Rep. Alexandria Ocasio-Cortez might have some explaining to do amid new allegations that Brand New Congress PAC hired and paid her boyfriend Riley Roberts after they became a part of her campaign.

The Coolidge Reagan Foundation, a conservative non-profit, filed a complaint to the Federal Elections Committee earlier this week. “It is totally legal, as a candidate, to hire family members, people you know to work for you. But they didn’t do that,” Coolidge Reagan Foundation attorney Dan Backer told the New York Post.

“Instead of paying him directly, they paid him through an intermediary — in order to obscure the fact that they paid him. The FEC should investigate and find out if that’s the case. That’s the allegation.”

The PAC has denied any violation of finance laws and told Fox News that Roberts, “was hired through a two-month trial period, beginning on August 3, 2017, and worked through the end of September 2017. Services to the Brand New Congress PAC consisted of advertising strategies for potential growth, developing metrics, and aiding in execution of strategy to increase brand awareness for the PAC as a whole.”

Last week, Ocasio-Cortez denied wrongdoing using her Twitter, posting on the website, “No, I don’t shadily pay my boyfriend. Come on & VET.”
