EXCLUSIVE — A senior analyst at the largest office within the Executive Office of the President, the Office of Management and Budget, participated in a Friday rally against President Joe Biden led by a climate group behind extremist anti-oil protests.

Climate Defiance, an organization linked to a left-wing dark money network deploying unorthodox protest methods against fossil fuels, gathered on Friday morning outside the Democratic National Committee’s headquarters in Washington, D.C., to demand Biden not run for reelection. In attendance at that same event was an eight-year veteran legislative analyst named Daniel Michelson-Horowitz at the powerful Office of Management and Budget, the Washington Examiner has confirmed.
