The whistleblower complaint about President Trump centers on Ukraine, according to people familiar with the matter
The complaint was made by a U.S. intelligence official who previously worked in the White House. Weeks before the complaint was filed, Trump spoke with Ukrainian President Volodymyr Zelensky. That call is already under investigation by House Democrats examining whether Trump and his attorney Rudolph W. Giuliani sought to manipulate the Ukrainian government into helping Trump��s reelection campaign.
