In the Radio Free Europe/Radio Liberty interview clip, Bolton made no mention of any illicit quid pro quo, and acknowledged, as Republicans have claimed, that combating "corruption" in Ukraine was a "high priority" for the Trump administration.
Bolton also called Trump's communications with Ukrainian President Volodymyr Zelensky "warm and cordial," without mentioning any misconduct. It seemingly contradicted reported assertions in Bolton's forthcoming book that Trump explicitly told him he wanted to tie military aid to Ukraine to an investigation into Joe and Hunter Biden. (Zelensky has said his communications with Trump involved no pressure for any investigation.)
Separately, Fox News has identified clips of Rep. Adam Schiff, D-Calif., now the lead House impeachment manager, in which he says Bolton had a distinct "lack of credibility" and was prone to "conspiracy theories." This week, Schiff said Bolton needed to testify in the impeachment trial as an important and believable witness.
"This is someone who's likely to exaggerate the dangerous impulses of the president toward belligerence, his proclivity to act without thinking, and his love of conspiracy theories," Schiff told MSNBC's Rachel Maddow on March 22, 2018, when Trump named Bolton national security adviser.
"And I'll, you know, just add one data point to what you were talking about earlier, John Bolton once suggested on Fox News that the Russian hack of the DNC [Democratic National Committee] was a false flag operation that had been conducted by the Obama administration," he said. "So, you add that kind of thinking to [former U.S. attorney] Joe diGenova and you have another big dose of unreality in the White House."
