SAN JOSE — With a court hearing scheduled next week in the midst of a tight race, congressional hopeful Ro Khanna filed papers dismissing incumbent rival Mike Honda’s accusations in a lawsuit that his campaign illegally accessed his opponent’s donor records.

Khanna, a Fremont-based attorney seeking to oust fellow Democrat Honda, of San Jose, said in the 81-page court filing that he had no knowledge of any donor database breaches alleged in Honda’s lawsuit, amplifying his response from the day the suit was filed late last month with more details. Six of the seven examples of allegedly stolen donor email addresses, Khanna said in the court filing, can be traced to his own previous communications with those people, and the other can be easily found through an internet search.

Honda’s campaign is asking a federal judge for an injunction that would order all materials be returned and expelled from Khanna’s databases, and it may seek compensatory and exemplary damages as well. It names Khanna as a defendant as well as Brian Parvizshahi, the 26-year-old former campaign manager at the center of the accusations, with a hearing scheduled for Tuesday.

In a separate filing, Parvizshahi downplayed Honda’s charge that he continued to access donor records he had been permitted to view as a summer intern for a Honda campaign consultant before leaving that job and joining Khanna.

“They’re calling him a Russian hacker, saying it’s like Watergate,” said Parvizshahi’s attorney Renato Mariotti. “He was receiving pop-up notifications that these files were there — these things pop up on your screen and you look out of curiosity, is that a crime? Because that’s what we’re talking about here.”

Honda’s campaign said it is indeed a crime, a serious one that they can’t quantify because they don’t know how many documents Parvizshahi had access to and how they were used.

Honda attorney Gautam Dutta said just accessing the files is criminal and added that the Dropbox digital fingerprints that Parvizshahi left “show intent not just to browse” and indicate he’d stored some of the documents.

Khanna said Wednesday that they don’t have anything to return or destroy and they’ve already cleared out any emails that appear in both their contact lists and the one provided by Honda as part of the lawsuit.

Khanna’s attorney David Berger said they have 135,000 names in their database, and when compared with the 3,280 in the one they’re accused of poaching, there’s an overlap of 418 names.

“Of course there’s overlap,” Berger said. “They’re both Democrats running in the same district.”

Honda spokesman Vedant Patel said Parvizshahi’s quick resignation the same afternoon the lawsuit was filed suggests wrongdoing.

“You can’t claim you’re innocent and then take measures to fix a violation of the law,” said campaign manager Michael Beckendorf.

Khanna called Honda’s lawsuit a “Hail Mary” by a candidate who is facing defeat come November after an unexpected 1.7-percentage-point loss in the June primary, something to distract voters from the ongoing and unresolved ethics probe involving his taxpayer-funded office staff being involved in campaigning, which is illegal.

Honda’s camp said the database breach proves that Khanna is the one with ethical lapses.

“There’s very little that a campaign manager does that the candidate is not directly involved in,” Patel said. “The question is how much was he involved in; how was he involved in using this information?”

According to an affidavit by Parvizshahi, he worked for the political consulting firm Arum Group as an intern in May 2012, at which time he was given access to folders containing information about contributors to Honda’s campaigns. Parvizshahi left Arum amicably after a couple of weeks to join the re-election campaign for President Barack Obama, later joining Khanna’s campaign in January 2014. Honda has retained the Arum Group’s founder as a consultant since 2005.

In his statement, Parvizshahi said he never told Khanna about his Dropbox access, nor was he instructed to access the files contained therein. He added that “to the best of my recollection, at no time after my resignation from Arum Group, did I ever knowingly or intentionally print, download, edit or otherwise modify any content in the Arum Dropbox.”

Mariotti said Parvizshahi is “absolutely devastated” by the accusations.
