The Justice Department has sued to block a proposed $85 billion merger between AT&T and Time Warner, setting the stage for one of the biggest anti-trust lawsuits in decades. The merger would give AT&T control over Warner Bros. film and television studios, along with CNN, TNT, HBO and many other brands. Many say the Justice Department lawsuit could be politically motivated, as it comes after President Trump has spent months threatening and disparaging CNN, which is owned by Time Warner.
