AT&T is looking to discredit the Department of Justice’s lawsuit to block its proposed $85 billion merger with Time Warner by proving that the government’s decision is politically motivated. A U.S. district court judge will decide today if they have a case.

Why it matters: If the judge rules in AT&T’s favor, it will mean that President Trump’s personal and public vendetta against CNN, which is owned by Time Warner, is working against him.

Where it stands: The judge is currently weighing whether the government is being transparent enough about any communications between the White House and DOJ. The key is whether the White House is attempting to influence the DOJ’s decision, which would strengthen AT&T’s position in court.
