“The official stated that there was already a conversation underway with White House lawyers about how to handle the discussion because, in the official’s view, the president had clearly committed a criminal act by urging a foreign power to investigate a U.S. person for the purposes of advancing his own re-election bid in 2020,” the C.I.A. officer wrote.

The document provides a rare glimpse into at least one of the communications with a White House official that helped prompt the whistle-blower’s formal complaint to the intelligence community inspector general detailing a broad pressure campaign on Ukraine by Mr. Trump, administration officials and his personal lawyer.

The complaint and a reconstructed transcript released by the White House formed the basis of the House impeachment inquiry into Mr. Trump.

The inspector general, Michael Atkinson, handed the two-page memo over to Congress last week along with other documents that shed light on the whistle-bl ower and his actions . A person familiar with their contents, which Fox News first reported, described them to The New York Times. A lawyer for the whistle-blower did not comment.

The whistle-blower, who relied on “multiple U.S. government officials” for his complaint, said that Mr. Trump was “using the power of his office to solicit interference from a foreign country in the 2020 U.S. election.”
