The lawyer's for Elliot Broidy, a top fundraiser for US President Donald Trump, have issued 40 subpoenas as part of an escalating legal battle against Qatar, whom he blames for a hack into his private emails, Reuters reported.
The subpoenas – which were sent to internet service providers and lobbying firms, among others – come as part of a civil lawsuit filed by Broidy in Los Angeles accusing the Gulf Arab country of being behind the theft and subsequent leak of a raft of emails.
Broidy alleges Qatar leaked the emails in retribution for his support of Saudi Arabia and the United Arab Emirates, which are currently embroiled in a year-long diplomatic row and blockade of their Qatari neighbour.
Gulf powers are currently waging a fierce and multi-billion dollar battle for influence in the Trump administration, in an attempt to align Washingtons policies in the Gulf and elsewhere in the Middle East with their own.
The leaked emails were seen by several media outlets. They showed Brody and Lebanese-American businessman George Nader cultivating links with Saudi Arabias Crown Prince Mohammed bin Salman and the UAEs Crown Prince Mohammed bin Zayed as part of a shadowy lobbying effort to isolate Qatar.
The case also names Nicolas Muzin and his lobbying firm Stonington Strategies LLC as defendants.
Qatar and Muzin deny involvement in the email hack.
On Thursday, Broidy is expected to file an amended complaint, expanding the list of defendants with people suspected of carrying out the hack or disseminating the material, Reuters reported.
A subpoena viewed by Reuters demanded the recipient hand over any documentation of communications linked with Broidy with several public relations and lobbying firms, some of which are listed as Qatari foreign agents.
According to Reuters, one recipient was Avenue Strategies Global LLC, a lobbying firm founded by Barry Bennett and former Trump campaign manager Corey Lewandowski.
Bennet was an adviser to the Trump campaign. Lewandowski had left the firm by the time the Qatari embassy hired it as a client.
A source told Reuters he believed many of the lobbying firms involved would refuse the subpoenas requests and are likely the challenge them in court.
