The Chicago Sun Times reports that federal agents removed everyone from the office of Chicago Finance Committee Chairman Ed Burke Thursday morning, covering the floor-to-ceiling windows with brown paper…

Burke worked for Trump for more than a decade doing property tax work.

Burke’s law firm of Klafter & Burke has worked with Trump’s companies repeatedly to reduce the property tax that Trump Tower and his other properties in Chicago have had to pay, according to the Sun Times.

Over his 12 years working for Trump, Burke was allegedly able to cut the property taxes on the downtown tower by more than $14 million.
