The White House on Wednesday released a summary of the July 25 phone call in which President Donald Trump asked Ukraine President Volodymyr Zelensky to look into former Vice President Joe Biden and his son Hunter.

The notes were released a day after House Speaker Nancy Pelosi announced she was launching an impeachment inquiry related to the call, including the Trump administration's refusal to release a complaint by an intelligence community whistleblower that is believed to be related to the call.

During the call, Trump references a purported probe by a Ukrainian prosecutor of a Ukraine natural gas company on whose board Hunter Biden had served.

"There's a lot of talk about Biden's son, what Biden stopped the prosecution and a lot of people want to find out about that, so whatever you can do with the attorney general would be great," Trump said to Zelensky in the call, according to the White House memo.

Trump then said, "Biden went around bragging that he stopped the prosecution, so if you can look into it, it sounds horrible to me."

Biden, who is seeking the Democratic nomination for president, said Tuesday that Congress will have "no choice" but to impeach Trump if the president stonewalls Congress about his contacts with Ukraine.

Trump said Tuesday he had "authorized the release tomorrow of the complete, fully declassified and unredacted transcript of my phone conversation" with Zelensky.

However, what was released Wednesday as a five-page summary of that call, which lasted around a half hour, and not a full verbatim transcript of the call.
