In 2018, The Hill began labeling Solomon's articles as opinion. Then, in March and April 2019, Solomon published a series of columns alleging conspiracies involving Democrats and Ukraine.
One of his key sources, apparently, was former New York City Mayor Rudy Giuliani, Trump's personal lawyer. According to the New York Times, Giuliani, whose activities were central to the administration's efforts to get an investigation launched into Trump's political rivals, gave Solomon a cache of information on Biden, his son Hunter and special counsel Robert Mueller's Russia probe.
"I really turned my stuff over to John Solomon," Giuliani told the New York Times.
When Fiona Hill, Trump's former top Russia expert, was asked during private testimony how she first learned about Giuliani's "interest" in Ukraine, she mentioned Solomon, whose columns outlined the same conspiracies that Giuliani was actively pushing on Twitter and TV.
Senior State Department official George Kent later testified that what he had described as the "campaign of slander" against former U.S. ambassador to Ukraine Marie Yovanovitch began with one of Solomon's articles and ended with Yovanovitch's removal.... Kent testified that Solomon's article "was, if not entirely made up in full cloth, it was primarily non-truths and non-sequiturs." He later said he had "every reason to believe it was not true."
Vindman said all the "key elements were false," noting that Solomon's columns "smelled really rotten" before joking, "His grammar might have been right."
Similar objections have been raised in testimony about two articles Solomon published about Biden in April, which were also referenced in the whistleblower's complaint. Solomon's April columns asserted that then-Vice President Biden forced Ukraine to fire former prosecutor general Viktor Shokin in order to stop an investigation into Burisma Holdings, a gas company for which Hunter Biden served on the board. Solomon wrote that Biden withheld aid dollars from Ukraine as leverage to get Shokin removed.
There's no evidence of wrongdoing by either Biden, as we've noted before. It's not clear that the long-dormant investigation into Burisma had been reopened, as Solomon claimed, and Western leaders and institutions were united in wanting Shokin removed.
Solomon's columns also alleged misconduct in Ukraine by Democratic donor George Soros and claimed, without much evidence, that Democrats coordinated with Ukrainian officials to interfere in the 2016 election by sharing dirt on Trump and reviving a 2014 investigation into former Trump campaign manager Paul Manafort, who had ties to the country's old, pro-Russia regime.
These claims are unproven, and the U.S. intelligence community has concluded that it was Russia " not Ukraine " that interfered in the 2016 election, with the intent of helping Trump. www.politifact.com
