From CBS News:
Washington — The diplomatic official who allegedly overheard President Trump ask about the status of “investigations” soon after his July phone call with the Ukrainian president is expected to appear before House lawmakers for a closed-door hearing on Friday.
David Holmes is the staffer referenced by diplomat Bill Taylor in testimony before the House Intelligence Committee on Wednesday, three sources familiar with the matter tell CBS News. Holmes is a counselor for political affairs at the U.S. embassy in Kiev, according to the embassy’s website.
At the first public hearings of the impeachment inquiry, Taylor testified that a member of his staff, whom he did not name, was with U.S. Ambassador to the E.U. Gordon Sondland at a restaurant on July 26 when the ambassador placed a call to Mr. Trump.
“The member of my staff could hear President Trump on the phone, asking Ambassador Sondland about ‘the investigations,'” Taylor, the chargé d’affaires at the U.S. embassy in Kiev, said in his opening statement. “Ambassador Sondland told President Trump that the Ukrainians were ready to move forward.”
Taylor said the staff member, now known to be Holmes, asked Sondland after the call what the president “thought about Ukraine.”
“Ambassador Sondland responded that President Trump cares more about the investigations of [Joe] Biden, which [Rudy] Giuliani was pressing for,” Taylor said, indicating he was not aware of the conversation at the time of his deposition in October, and only learned about it last Friday.
