On Wednesday, Zelensky tweeted a photo of him and Trump, along with their wives, Olena and first lady Melania Trump, during a reception Tuesday night at the United Nations in New York City.

Zelensky’s tweet came with the caption that the two leaders “talked” during the event. It’s probably certain that they will talk later Wednesday about the Trump administration releasing a rough, unclassified “transcript” of their controversial phone call this past summer.

In the call, Trump raised unsubstantiated allegations that former Vice President Joe Biden sought to interfere with a Ukrainian prosecutor’s investigation of his son, Hunter. The younger Biden served on the board of a Ukrainian gas company while his father spearheaded President Obama’s administration diplomatic affairs with Kyiv.

While the timing raised corruption concerns, there has been no evidence of wrongdoing by either Biden or his son.

Zelensky’s tweet came a day after House Speaker Nancy Pelosi made Trump just the fourth American president to face an impeachment inquiry. Trump called the inquiry Wednesday, “the single greatest witch hunt in American history.”

Meanwhile, Pelosi reiterated to reporters on Capitol Hill Wednesday that Trump’s actions deserve an investigation and possible impeachment.

“The fact is, the President of the United States, in breach of his constitutional responsibilities, has asked a foreign government to help him in his political campaign at the expense of our national security, as well as undermining the integrity of our elections,” Pelosi said. “That cannot stand. He will be held accountable. No one is above the law.”

Utah Senator Mitt Romney told reporters that he read the transcript and apparently didn’t like what he saw.

“It remains troubling in the extreme. It’s deeply troubling,” said Romney, who was the 2012 Republican nominee for president. “Clearly what we’ve seen from the transcript itself is deeply troubling.”

Romney, one of the few Republicans to express concern about the transcript publicly, also refused to criticize Pelosi’s actions.

“That’s not advice I’m going to be providing to the House or to the Speaker. She’s able to do what she feels is right. That’s up to her,” Romney said. “At this stage, the process is to continue to gather information but clearly what we’ve seen from the transcript itself is deeply troubling.”
