A whistleblower complaint about President Trump made by an intelligence official centers on Ukraine, according to two people familiar with the matter, which has set off a struggle between Congress and the executive branch.
The complaint involved communications with a foreign leader and a “promise” that Trump made, which was so alarming that a U.S. intelligence official who had worked at the White House went to the inspector general of the intelligence community, two former U.S. officials said.
Two and a half weeks before the complaint was filed, Trump spoke with Ukrainian President Volodymyr Zelensky, a comedian and political newcomer who was elected in a landslide in May.
