President Trump, speaking about the just-released transcript of his July call with the Ukrainian president, insisted there was "no pressure."

“It was a friendly letter," Trump said referencing the transcript. "There was no pressure, the way you had it built up, that call, it was going to be the call from hell."

He added: "It turned out to be a nothing call other than a lot of people said, 'I never knew you could be so nice.'"

Trump said the impeachment inquiry is a "witch hunt."

"Just so you understand, it is the single greatest witch hunt in American history, probably in history, but in American history," he said.

What the transcript shows: President Trump repeatedly pushed for the Ukrainian president Volodymr Zelensky to reopen an investigation of his potential 2020 rival, former Vice President Joe Biden and his son, and asked the Ukrainian leader to work with Rudy Giuliani and Attorney General William Barr on the issue.
