 In June 2011 the House Ethics Committee began an investigation after receiving information suggesting that two of Chu's top aides had directed staffers to do campaign tasks during regular work hours.In the course of the investigation it was found that Chu had sent two emails to her staff on how to respond to aspects of the Ethics Committee's inquiry.While the Committee found no evidence to support that Chu was aware of the actions of her staff, they did find that the emails represented actions that interfered with the committee's investigation of the matter, and on December 11, 2014, Rep. Chu was formally reprimanded by the House Ethics Committee for interfering with their investigation of her office.
