Attorneys for CIA Officer Behind Trump Complaint Say They Now Represent ‘Multiple Whistleblowers’

WASHINGTON—The legal team representing the Central Intelligence Agency officer behind the complaint that helped spark an impeachment inquiry into President Trump is now advising “multiple whistleblowers,” the attorneys said Sunday.

The existence of at least one additional whistleblower could complicate President Trump’s efforts to counter the impeachment proceedings building against him in Congress. Mr. Trump repeatedly has sought to attack the credibility and motive of the first individual who filed a formal whistleblower complaint in August.

“I can confirm that my firm and my team represent multiple whistleblowers,” Andrew Bakaj, the lead attorney for the first whistleblower, said in a tweet. “No further comment at this time.”
