Washington (CNN) The intensifying Ukraine controversy and the House Democratic impeachment inquiry continue to drive an unyielding barrage of news in Washington.

Here's the latest:

Trump's private fury over impeachment spills into public view

There was little strategy evident as Trump railed against Democrats and the media during public events with Finnish President Sauli Niinisto. And there were few new answers that might help alleviate the situation he finds himself in after asking a foreign counterpart to investigate a political rival.

As a reminder, a whistleblower complaint released last week alleges Trump abused his official powers "to solicit interference" from Ukraine in the 2020 election and that the White House took steps to cover it up. Trump has denied any wrongdoing.

A rough transcript released by the White House shows Trump repeatedly pushed Ukrainian President Volodymyr Zelensky in a July phone call to investigate Joe Biden, Trump's potential 2020 political rival, and his son Hunter Biden.

There is no evidence of wrongdoing by Joe or Hunter Biden.

State Department inspector general gives Congress documents that Giuliani provided

State Department Inspector General Steve Linick provided Congress on Wednesday with documents that included materials Trump's personal lawyer, Rudy Giuliani, had given to the department earlier this year containing unproven claims about Joe and Hunter Biden.

The documents, which were obtained by CNN, include claims against the Bidens that formed the basis of Trump's accusations in his July call with Zelensky, as well as accusations against former US Ambassador to Ukraine Marie Yovanovitch, who was recalled earlier this year and whom Trump also criticized in the call.

In addition, the packet contains internal State Department emails from officials discussing articles critical of Yovanovitch, calling some of it a "fake narrative."

Giuliani told CNN on Wednesday evening that some of the documents provided to Congress by the State Department's inspector general had originated with him. Giuliani gave the documents to the White House, which then passed them to Secretary of State Mike Pompeo, according to a source familiar with the matter.

Giuliani said that in late March, he had "routed" what he called an "outline" of allegations against Biden, as well as Yovanovitch, to Pompeo's office.

Justice Department tells White House to preserve notes of Trump's calls with foreign leaders

The question of whether the White House was preserving the information had arisen in federal court Tuesday, following government-transparency and historical archivist groups' emergency request to maintain the notes from the Trump-Zelensky July call and other Trump discussions with world leaders.

"Defendants today instructed relevant personnel to preserve the information," Justice Department lawyers told a federal judge in a court filing.

GOP concern grows beneath the impeachment spin

GOP sources tell CNN they have a good reason for that fear. They have no idea what else House Democrats' investigation will uncover or what comes next.

While phrases like "witch hunt" and "hoax" worked for the President politically during the investigation by special counsel Robert Mueller, concerned GOP sources -- more than half a dozen, including some in leadership who are talking to and hearing from the rank and file -- tell CNN that they worry the President isn't comprehending what they believe to be true, that this is different.

Trump demanded a Ukraine policy review in June. Months later, no one will say what happened.

A senior administration official said the directive to freeze Ukrainian aid came in June, earlier than has previously been reported -- a move that continues to baffle US officials. Four months later, it is still unclear exactly why the President ordered the review or what was under review.

Energy Secretary Rick Perry says he'll cooperate with Congress on Ukraine questions

"I'll just briefly say we're going to work with Congress and answer all their questions," Perry said at a department event on artificial intelligence and energy.

Ukraine's ex-president says he had no knowledge of prosecutor's offer to help Trump

In a brief exchange in the capital, Kiev, on Wednesday, Poroshenko said he had no information and did not send one of his general prosecutors, Yuriy Lutsenko, to meet with Giuliani.

Giuliani says he twice met with Lutsenko -- in New York in January 2019, then in Warsaw in February.
