President Trump, speaking from the Oval Office today, said he knew "many people were on the phone" during his July call with Ukraine's leader.

"I knew many people were on the phone. Not only were many people on the phone, we had stenographers on the phone taking it down word for word," he said.

Trump went on to say the whistleblower "was wrong."

"The only thing that matters is the transcript of the actual conversation that I had with the president of Ukraine. It was perfect," he said.
