President Trump’s Air Force One video trashing Mayor Bill de Blasio may have violated law

President Trump tried to give his latest attack on Mayor Bill de Blasio an aura of authority — but he may just have broken the law in the process.

While jetting on Air Force One to a political fundraising event, Trump tried to look presidential by sitting behind a desk as he blasted de Blasio as soft on crime and quick on taxes.

But look a bit closer and an ethics watchdog spots a big problem for Trump in the video. Over Trump’s left shoulder, affixed above a window, is the presidential seal.
