ProPublica hit back on Monday after White House press secretary Sean Spicer dismissed its reporting on a newly surfaced detail in President Donald Trump’s trust agreement as an unsubstantiated claim from a “left-wing blog.”

ProPublica on Monday reported that Trump added a clause to the agreement that allows him to withdraw funds at any time and from any of his businesses without publicly disclosing that transaction.

“I’m not aware that there was any change,” Spicer said when asked about the report. “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.”

“Since we’re actually in the biz of facts, we figured we’d respond,” ProPublica tweeted Monday evening.

ProPublica went on to link Spicer to the revised clause in the trust document, its report on the revision and previous ProPublica reporting critical of the administrations of both Trump and President Barack Obama.

“So any other facts you’d like to know, @seanspicer?” the thread concluded.
