The Wall Street Journal published a pro-Donald Trump op-ed without disclosing that its author, Anthony Scaramucci, works as part of the Trump campaign’s national finance committee.

The Journal wrote that Scaramucci is “the founder and co-managing partner of SkyBridge Capital,” failing to mention that he joined the Trump campaign as part of Trump’s “nascent national finance committee.” According to The Washington Post, Scaramucci was “one of the first traditional bundlers to join the Trump campaign.”

In his May 15 op-ed, titled, “The Entrepreneur’s Case For Trump,” Scaramucci hyped Trump as a “pragmatic entrepreneur,” “team builder,” and a candidate with “empathy” who can win. Scaramucci concluded his piece urging his “fellow Republicans to listen to the will of people” and “unite not only for the good of the party, but for the good of the nation”.

Trump responded to Scaramucci’s op-ed, tweeting, “Thank you, Anthony Scaramucci”:

During the 2012 presidential campaign, the Journal repeatedly failed to disclose op-eds written by advisers to then-GOP presidential nominee Mitt Romney. A Media Matters study found that 70 percent of the Journal’s op-eds written by Romney advisers lacked disclosure.
