Fox News and Fox Business have described Serrano variously as a Republican strategist, a crisis-management expert and a former adviser to President George H.W. Bush since he began appearing on the networks in 2014.

But Serrano has had another role this spring, one that wasn’t disclosed to viewers as he was touting Trump: His firm was a paid consultant to the president’s 2020 reelection campaign.

Federal disclosure forms filed by the Trump committee Saturday show that it paid Serrano’s firm, ProActive Communications, a total of $30,000 for “communications consulting.” The records indicate that it paid $20,000 on April 17 to the company, based in Leesburg, Va., and another $10,000 on May 30.
