When the Trump administration took office early last year, hundreds of staffers from lobbying firms, conservative think tanks and Trump campaign groups began pouring into the very agencies they once lobbied or whose work they once opposed.

Today we’re making available, for the first time, an authoritative searchable database of 2,475 political appointees, including Trump’s Cabinet, staffers in the White House and senior officials within the government, along with their federal lobbying and financial records. Trump Town is the result of a year spent filing hundreds of Freedom of Information Act requests; collecting and organizing staffing lists; and compiling, sifting through and publishing thousands of financial disclosure reports.

Here’s what we found: At least 187 Trump political appointees have been federal lobbyists, and despite President Trump’s campaign pledge to “drain the swamp,” many are now overseeing the industries they once lobbied on behalf of. We’ve also discovered ethics waivers that allow Trump staffers to work on subjects in which they have financial conflicts of interest. In addition, at least 254 appointees affiliated with Trump’s 2016 presidential campaign and at least 125 staffers from prominent conservative think tanks are now working in the federal government, many of whom are on teams to repeal Obama-era regulations.

Drilling down even further, at least 35 Trump political appointees worked for or consulted with groups affiliated with the the billionaire libertarian brothers Charles and David Koch, who also have a network of advocacy groups, nonprofits, private companies and political action committees. At least 25 Trump appointees came from the influential Heritage Foundation, a conservative think tank founded in 1973, and at least two came from Heritage Action, its related political nonprofit. Heritage says the Trump administration, in just its first year, has enacted nearly two-thirds of its 334 policy recommendations.
