Whistleblower accuses White House of Ukraine call cover-up

WASHINGTON (AP) — White House officials took extraordinary steps to "lock down" information about President Donald Trump's summertime phone call with the president of Ukraine, even moving the transcript to a secret computer system, a whistleblower alleges in a politically explosive complaint that accuses the administration of a wide-ranging cover-up.

The whistleblower, in a 9-page document released Thursday , provides substantial new details about the circumstances of the phone call in which Trump repeatedly spoke of how much the U.S. had aided Ukraine and encouraged new President Volodymyr Zelenskiy to help investigate political rival Joe Biden and his son.

Accusations of efforts to pressure the leader of a foreign nation to dig for dirt on a potential 2020 Trump rival are now at the heart of a House impeachment inquiry against the president. The whistleblower's official complaint alleges a concerted White House effort to suppress the transcript of the call, and describes a shadow campaign of foreign policy efforts by the president's personal lawyer Rudy Giuliani that unnerved some senior administration officials who felt he was circumventing normal channels.

"In the days following the phone call, I learned from multiple U.S. officials that senior White House officials had intervened to 'lock down' all the records of the phone call, especially the official word-for-word transcript of the call that was produced as is customary by the White House situation room," the complaint says.

The previously secret document, with its detail and clear narrative, is likely to accelerate the impeachment process and put more pressure on Trump to rebut its core contentions and on his fellow Republicans to defend him or not. It also provides a road map for Democrats to seek corroborating witnesses and evidence , which will complicate the president's efforts to characterize the findings as those of a lone partisan out to undermine him.

In response, Trump threatened "the person" who he said gave information to the whistleblower as he spoke at a private event in New York with staff from the U.S. mission to the United Nations.

"Who's the person who gave the whistleblower the information? Because that's close to a spy," Trump said in audio posted by The Los Angeles Times. "You know what we used to do in the old days when we were smart? Right? The spies and treason, we used to handle it a little differently than we do now."

On his Twitter account, Trump insisted the entire controversy is political: "The Democrats are trying to destroy the Republican Party and all that it stands for. Stick together, play their game and fight hard Republicans. Our country is at stake." His tweet was in all capital letters.
