A hearing in a Pennsylvania federal court Tuesday regarding President Donald Trump’s effort to block certification of the state’s election results ran into a problem that caused it to delay proceedings for almost an hour. The issue? No one could hear anything.

The U.S. District Court for the Middle District of Pennsylvania previously set up a phone number for anyone to dial and listen to proceedings in Donald J. Trump for President v. Boockvar after limiting physical access to its Williamsport, Pennsylvania, courthouse. But right from the start, the live audio didn’t go smoothly.
