Schiff and the Chairman of the Intelligence Committee of publishing "Doctoral Records" by administrative officials who testified behind closed doors, even though he did not provide any evidence.
In another tweet, the president called for scams against Schiff and the C.I.A. Whistleblower who announced on July 25 a call between Mr. Trump and President Volodymyr Zelensky of Ukraine.

Trump has repeatedly said that the call was "perfect" on July 25th. On Monday evening, Mr. Trump said in a tweet that he wanted to publish the transcript of an earlier call with Mr. Zelensky, claiming to be the most transparent president in history.
"I'm sure you'll find it tempting!" Wrote Trump's efforts to use the power of his office to use Ukraine in a way that could help him in the 2020 election.
