EXCLUSIVE – Immediately after learning second-hand information from a White House official about President Trump’s July 25 phone call with the president of Ukraine, the first whistleblower wrote a dramatic personal memo, saying the White House official characterized the call as “crazy” and “frightening,” Fox News has learned.

In the two-page, single-spaced memo on July 26, the day after the Trump-Zelensky phone call, the whistleblower wrote: “The following is a record of a conversation I had this afternoon with a White House official about the telephone call yesterday morning between President Trump and Ukrainian President Volodymyr Zelensky.”

The whistleblower wrote that the conversation with the unnamed White House official “only lasted a few minutes, and as a result, I only received highlights.”
