House Democrats may call new impeachment witnesses if Senate doesn't

Key House Democrats pressing the Senate to hear from new witnesses in President TrumpDonald John Trump Where do we go from here? Conservation can show the way Gov. Ron DeSantis more popular in Florida than Trump Sotomayor accuses Supreme Court of bias in favor of Trump administration MORE’s impeachment trial are leaving the door open to another possibility: calling those witnesses themselves if Senate Republicans do not.

House Democrats impeached Trump last month on two charges related to his handling of foreign policy in Ukraine, but their investigations into the issue remain open even as the spotlight turns to the launch of the Senate trial.

Democrats in both chambers are hoping the emergence of new evidence and eyewitness offers to testify will force Senate GOP leaders to consider the unexplored information, including captivating details of Trump’s pressure campaign recently provided by Lev Parnas, a Soviet-born businessman with close ties to Trump's personal lawyer, Rudy GiulianiRudy Giuliani Former US ambassador Yovanovitch lands a book deal: report Kerry responds to Trump accusation he violated Logan Act: 'Another presidential lie' Giuliani worked for Dominican Republic candidate amid Ukraine efforts: report MORE.

Most Senate Republicans, taking cues from Senate Majority Leader Mitch McConnell

Yet even if McConnell has his way and prevents new witnesses from appearing, they may find a stage in the House, where a number of Democrats are already advocating for their testimony if they’re silenced by the Senate.

“We would be remiss in the House of Representatives not to follow this trail to its conclusion. And Parnas has emerged as an important figure in this criminal conspiracy to force or coerce a foreign government to help Trump's reelection campaign,” said Rep. Hank Johnson

With Democrats hoping to maximize the pressure on Senate Republicans through the trial phase, Judiciary members have not discussed that strategy in any depth, Johnson emphasized. But it’s likely to gain favor with committee leaders, he said, if Senate Republicans deny new and willing witnesses a voice.

“They have their eye on it,” Johnson said.

But he left the door wide open to doing so, vowing that Democrats will charge ahead with their Ukrainian investigation “if we're feeling that we're being played and that they're not being forthcoming with the truth.”

“We're not going to just say, ‘OK, we've disposed of it and now the ball’s in their court and there’s nothing left for us to do.’ I think quite the contrary,” Engel said. “The more we hear, and the more things come out, the more resolute we are to make sure that we're dealing with the truth, and that it’s not being swept under the rug.”

The comments came the same day that House Democrats, led by Intelligence Committee Chairman Adam Schiff

The trial begins formally on Tuesday.

The Democrats' impeachment case rests on the argument that Trump violated his office in withholding almost $400 million in military aid to Ukraine last summer to pressure the country's president, Volodymyr Zelensky, to open investigations into the 2016 elections and the son of former Vice President Joe Biden

Throughout the months-long House investigation, lawmakers heard from a host of diplomats and national security officials — both current and former — with insights into Trump's campaign to win the investigations he sought from Ukrainian leaders. Many sounded warnings that the shadow foreign policy in Kyiv — led by Giuliani — prioritized Trump’s political interests even as it threatened U.S.-Ukraine relations and efforts to contain Russian aggression in the region.

This week, Parnas offered vivid new details of that campaign, providing Democrats with a trove of documents, phone records, emails and text-messages related to his communications with Giuliani, a disreputable Ukrainian prosecutor, an unstable Republican landscaper and others who participated in the effort to oust Marie Yovanovitch

Trump, for his part, has denied any connection to Parnas.

“I don’t know who this man is,” Trump said Thursday.

Parnas and another Soviet-born businessman, Igor Fruman, were both arrested in October and charged in New York on unrelated campaign finance charges. Given those legal troubles, many Republicans have dismissed Parnas as a potential witness, saying he simply lacks the credibility to be of any value in the case.

Democrats have a different view, noting that much of the information Parnas provided came in the form of concrete communications records and physical documents.

“But as a former law enforcement officer,” she quickly added, “I also know that we've been able to put some pretty strong cases together for people who ... have started on the wrong side, but decided to try to right their wrongs by cooperating with our state attorney. And that could be the situation here.”

“They may find him credible, may not, but it also may lead to other information," she said, urging the Senate to call him in.

Included in the records Parnas relinquished was a previously unknown May 10 letter from Giuliani to Zelensky asking for a 30-minute meeting — a request Giuliani said was made “with [Trump's] knowledge and consent.”

Trump last week denied any knowledge of the Giuliani letter. “But if he wrote a letter,” the president added, “it wouldn't have been a big deal.”

Aside from Parnas and Bolton, Democrats are also clamoring to hear testimony from a number of other administration officials, many of whom had declined to appear before the lower chamber last year after the White House blocked their participation.

Schakowsky said she wants to summon Giuliani to testify, while Johnson suggested Mick Mulvaney
