A U.S. district court judge will decide by Tuesday whether AT&T has the right to call the Justice Department's antitrust chief Makan Delrahim to the stand in the March trial over the government's law suit to block the merger with Time Warner.
Why it matters: The decision will determine whether AT&T has grounds to believe that the White House has interfered with the DOJ's merger review, which is supposed to be independent from the president. If the court rules in favor of AT&T, the government would have to hand over all communications between the White House and DOJ.
