An official complaint was filed Tuesday by a conservative watchdog group against Rep. Alexandria Ocasio-Cortez, D-N.Y., calling for an ethics investigation over her attendance at the recent Met Gala. 

The complaint was sent to the Office of Congressional Ethics to review if her ticket was donated or purchased. Met Gala tickets range from about $35,000 to $50,000. 

This would violate Clause 5 of Rule XXV of the Rules of the House of Representatives, also known as the “Gift Rule.” 

"There are serious questions about whether or not her ticket — donated or purchased with campaign funds — was permissible under the code of congressional ethics," the American Accountability Foundation said in a statement

"These rules exist for a reason. Without strict adherence, we run the risk of corruption in the halls of Congress and public officials serving others over their constituents. Government has a responsibility to its citizens, and integrity and accountability should be our foremost concern."

Whether the ticket was donated or purchased, Ocasio-Cortez runs the risk of violating clause 5 or violating FEC prohibitions on campaign funds being used for entertainment purposes.

The AAF claimed in the complaint that if an investigation is not properly done, “the American people are likely to lose faith in the ability of Congress to police its members.”
