WASHINGTON — A fundraiser for President Donald Trump who launched a lawsuit against Qatar accusing the Gulf country of hacking his emails updated the filing Thursday to target a cybersecurity firm and two of its executives.

Elliott Broidy alleges that the firm, Global Risk Advisors, introduced Qatar to "cyber mercenaries" to help with the hacking. Broidy filed the lawsuit in March alleging that hackers from Qatar broke into his email account at the start of this year and that Qatar's lobbying team in Washington then pushed the emails to journalists around the city in an effort to discredit Broidy.

Global Risk Advisors did not immediately respond to a request for comment. The suit names founder Kevin Chalker and Managing Director David Powell.

The lawsuit is part of an ongoing battle involving the United Arab Emirates, Saudi Arabia, Qatar and a host of Washington power players.

In January, investigators working with special counsel Robert Mueller detained Broidy's business associate, George Nader, at Dulles International Airport in January. Nader, a Lebanese-American who has worked as an adviser to the crown prince of Abu Dhabi, agreed to cooperate with Mueller's investigation into Russian interference in the 2016 U.S. election.

Broidy and Nader were the subjects of an investigation by The Associated Press this week that detailed how they orchestrated a multimillion-dollar lobbying campaign against Qatar while they sought contracts from the UAE and Saudi Arabia.

The story was based on interviews and leaked emails. As part of the lawsuit, Broidy has subpoenaed the AP for information about the source of the documents.

Broidy said in a statement Thursday that Qatar targeted him to keep him from speaking out.

"We believe it is also clear that I have been targeted because of my strong political views against Qatar's state sponsored terrorism and double dealing, and the fact that I was not shy about expressing my views," Broidy said.

In a statement, the embassy of Qatar in Washington called the claims in the lawsuit "fabricated and without merit."

"The facts show it was Mr. Broidy who conspired in the shadows against Qatar — not the other way around," the embassy said.
