Why Did Trump's Sons Put Money Into THIS Drone Company? (Ad)

Eric Trump and Donald Trump Jr. are reportedly backing an American drone manufacturer competing for a share of Washington's $1.1 billion push to expand low-cost drone production. The company has raised roughly $60 million, and the U.S. Air Force has agreed to buy its interceptor drones, according to Bloomberg. It is now merging with a tiny Nasdaq-listed company that owns two Florida golf courses. Veteran trader Tim Sykes says the unusual backing and strategic contracts make this drone play worth a closer look.tc pixel
