About 22 million households in the U.S. don’t have cable or streaming TV. They rely on local TV stations. Sinclair Broadcast Group is the largest owner of local TV stations in the US. It owns 193 stations in almost 80 markets. Employees of Sinclair say the company orders them to air segments that favor President Trump, and that it feeds them politically biased questions to ask in interviews. The company has a long history of trying to affect politics.
