WASHINGTON – The whistleblower complaint at the heart of the burgeoning controversy over President Donald Trump’s call with the Ukrainian president claims not only that Trump misused his office for personal gain and endangered national security but that unidentified White House officials tried to hide that conduct.

“In the course of my official duties, I have received information from multiple U.S. government officials that the President of the United States is using the power of his office to solicit interference from a foreign country in the 2020 U.S. election,” the whistleblower wrote in the complaint dated Aug. 12. The House Intelligence Committee released the seven-page document, which was directed to the heads of the House and Senate Intelligence committees, on Thursday morning. It also released a two-page appendix that was once classified and portions of which remain redacted.

“This interference includes, among other things, pressuring a foreign country to investigate one of the President’s main domestic political rivals. The President’s personal lawyer, Mr. Rudolph W. Giuliani, is a central figure in this effort. Attorney General [William P.] Barr appears to be involved as well,” the whistleblower wrote.

In that phone call, Trump pressed President Volodymyr Zelensky of Ukraine to investigate Joe Biden, who is seeking the Democratic nomination to run against Trump in 2020, and Biden’s son Hunter. Trump offered to enlist Barr’s help in that effort while dangling a possible visit to the White House, according to a rough transcript of the call released by the White House on Wednesday.

A spokeswoman for Barr has said that he did not know about the phone call until the whistleblower issue was raised, and that he had not spoken with Trump about assisting Ukraine with an investigation of Biden or his son.
