The Supreme Court has sided with the Trump administration in a case about the power of federal regulators over telecommunications companies. In an 8-1 ruling Thursday, the justices preserved one of the Federal Communications Commission’s key enforcement tools. Verizon and AT&T challenged multimillion-dollar penalties imposed after the agency determined that the companies failed to safeguard customer location data. The companies argued that the FCC's process was unconstitutional and they hoped to build on a line of Supreme Court cases limiting the power of federal agencies. The high court disagreed, though after the administration said companies didn't have to pay the fines right away.
