Solomon, a former reporter at The Associated Press and The Washington Post, has emerged as a key player in the Ukraine scandal, with testimony continuing this week about Trump and his allies put pressure on the country to open politically motivated investigations as military aid was withheld.

At Solomon's former employer, The Post, Paul Farhi wrote how the "conservative columnist helped push a flawed Ukraine narrative.” The New York Times last week dubbed Solomon “the man Trump trusts for news on Ukraine.”

Solomon has defended his work, including on Friday in an email to POLITICO. "I stand by each and every one of the columns that I wrote and that The Hill (both editors and lawyers) carefully vetted,” he wrote. “All facts in those stories are substantiated to original source documents and statements."

The journalist’s comments on Friday came after California Rep. Jackie Speier told Scott Wong, a senior staff writer at The Hill, that she wouldn’t speak to the publication because of its “reprehensible” decision to run Solomon’s columns, which she said lacked “veracity.” Speier also urged Wong to take her concerns to management.

Wong told Speier that “there are a lot of dedicated reporters at The Hill who do not share John Solomon’s views.” Last year, some journalists at The Hill complained to management about Solomon’s work, which was later moved from the news side to the opinion section. Solomon departed The Hill in September and later joined Fox News as a contributor.

Cusack did not mention Speier’s critique in Monday’s memo, which pointed to “recent Congressional testimony and related events” as the impetus for revisiting Solomon’s work.

The Hill’s top editor also reiterated that publication does “not condone sending material out before publication.” It’s been revealed in the impeachment inquiry that Solomon shared a draft of one of his Hill columns with allies of Trump lawyer Rudy Giuliani. “I do go over stories in advance,” Solomon told the Times in defending the practice.

Cusack concluded his note by emphasizing that “The Hill remains committed to giving voice to views across the political divide.”
