WASHINGTON — Shortly after being dismissed by Sean Spicer as nothing more than a “left-wing blog,” ProPublica — the nonprofit, Pulitzer Prize-winning, investigative news outlet — decided to give the White House press secretary a little lesson in fact.

1/ So @seanspicer just called us a “left-wing blog.” Since we’re actually in the biz of facts, we figured we’d respond w/ a few... — ProPublica (@ProPublica) April 3, 2017

During Monday’s press briefing, Spicer was asked about a ProPublica story, published earlier that morning, that said a change in a trust document allows President Donald Trump to “draw money from his more than 400 businesses, at any time, without disclosing it.”

“I’m not aware there was any change,” Spicer said. “Just because a left-wing blog makes the point of something changing, doesn’t mean it actually happened. I’m not aware that there was ever a change in the trust, and the idea that the president is withdrawing money at some point is exactly the purpose of why a trust is set up.”

ProPublica took Spicer to task in a series of tweets. It displayed the revised document, signed by Trump on Feb. 10, and noted that it had reached out to Trump and the White House for comment, but never received a response.

“What we do is hold people in power accountable, no matter who they are, or what names they call us,” the news outlet wrote. “We do it with facts.”

It proceeded to provide several about both the Trump and Obama administrations — just in case Spicer wanted to stand by his “left-wing blog” comment.
