Mike Honda, the congressman who represents a large portion of Silicon Valley, has sued his political opponent, Ro Khanna, under a federal anti-hacking law known as the Computer Fraud and Abuse Act.

Khanna, a former Department of Commerce official, is trying to unseat Honda in the upcoming November 2016 election. Honda, who has been a member of the House of Representatives for 15 years, previously defeated Khanna in a tight race in 2014.

The lawsuit claims that Brian Parvizshahi, who was Khanna’s campaign manager until Thursday evening, worked as an intern for a Honda campaign fundraising firm, Arum Group, for just a few weeks in the summer of 2012. However, when Parvizshahi left Arum Group, his access to a Dropbox account that included data on thousands of donors was not revoked.
