White House official says he heard US envoy push for investigation of Bidens
“He was calling for something, calling for an investigation that didn’t exist into the Bidens and Burisma,” Vindman said. The inquiry enters a critical phase next week when House committees hold impeachment hearings in public. “This was about getting a White House meeting,” he said. Democrats have sought Bolton’s testimony, but his lawyer, Charles Cooper, said in the letter that Bolton would not appear until a court rules on whether he should testify over objections from the White House. The White House previously has said it would not cooperate with the congressional investigation, which was triggered by a whistleblower complaint about a phone call on July 25 between Trump and Zelenskiy.
