One in five federal officials trade stock in companies their agencies oversee

Thousands of officials across the government’s executive branch reported owning or trading stocks that stood to rise or fall with decisions their agencies made, a Wall Street Journal investigation has found.

More than 2,600 officials at agencies from the Commerce Department to the Treasury Department, during both Republican and Democratic administrations, disclosed stock investments in companies while those same companies were lobbying their agencies for favorable policies. That amounts to more than one in five senior federal employees across 50 federal agencies reviewed by the Journal.
