President Trump went on the offensive today, openly accusing former Vice President Joe Biden of being "corrupt." Meanwhile, Trump himself faces claims that he asked Ukraine's President Volodmyr Zelensky to investigate the Democratic frontrunner.

"Joe Biden and his son are corrupt," Trump said, referring to unfounded claims that Biden's son was involved in a corruption scheme in Ukraine.

Trump then claimed — with no proof — that, "If a Republican ever did what Joe Biden did, if a Republican ever said what Joe Biden said, they'd be getting the electric chair right now."

The President also denied claims he put pressure on the Ukrainian leader by threatening to withhold US aid, saying, “I did not make a statement that ‘you have to do this or I’m not going to give you aid.’ I wouldn’t do that. I wouldn’t do that.”

"There was no pressure put on them whatsoever. I put no pressure on them whatsoever. I could have. I think it probably, possibly would have been OK if I did," he said.

Trump again was opaque on whether a transcript on his call with the Ukraine president will be released. However, he suggested that he hoped it would be released.

“It was a very nice call. I hope you get to see it and I hope you get to see it soon," Trump said.

Trump made the comments during a bilateral meeting with Polish President Andrzej Duda, where the two men signed what Trump called a “joint declaration on advancing defense cooperation.”
