WASHINGTON — President Donald Trump first came to Washington as an outsider who had campaigned against the permanent professional political class.

But new financial disclosure filings highlight the expansion of a political cottage industry that revolves around him, one that has been quite lucrative for some of his closest aides.

The filings, which are mandatory and appear to have been posted on the White House website Friday without any announcement, detail the finances of dozens of officials in the two years before they joined Trump’s administration.

Top Trump advisers including Dan Scavino, a deputy chief of staff, and Sergio Gor, director of the presidential personnel office, reported making more than $1 million each from media-related ventures linked to Trump.

Others — including the powerful White House chief of staff, Susie Wiles, and influential policy adviser Stephen Miller — reported being paid by think tanks or advocacy groups created to support Trump’s initiatives.

Two lawyers in the White House Counsel’s Office — the head of the office, David Warrington, and a deputy named Gary Lawkowski — worked at the law firm founded by Harmeet Dhillon, who is now serving as assistant attorney general. At the firm, Warrington and Lawkowski represented a Trump-allied Tennessee state legislator whom Trump pardoned in March for campaign finance-related crimes.

Warrington also represented a so-called fake elector from Michigan, and Lawkowski represented Trump, as well as Kash Patel, who is now serving as FBI director.

And a number of officials were paid as consultants by Trump’s own campaign and supportive political groups before entering the White House.

“This is Trump Inc.,” said Jonathan Guyer, who tracked the financial interests of incoming officials in the administration of President Joe Biden as a journalist for left-leaning publications, and is now tracking the interests of incoming Trump officials as an analyst at the Institute for Global Affairs, a think tank linked to Eurasia Group.

Guyer noted that many of the institutions and networks listed on the new filings emerged after Trump and his aides left office in 2021 under a cloud left by the Jan. 6, 2021, attack on the Capitol by Trump supporters.

Karoline Leavitt, the White House press secretary, said in a statement that the disclosures demonstrate the administration’s commitment to transparency rules and the willingness of aides to forgo private sector opportunities.
