The sophomore at Lake Brantley High School in suburban Orlando, Fla., said she heard an announcement over the intercom that the school was in a code red lockdown — it was a drill, but Storm said students were not told that. She and her classmates hid in the dark, behind an instrument locker.

"It was just really quiet. And we all sort of huddled together," Storm said.

Attorney General William Barr said there would be no obstruction of justice charges against the president stemming from the report by special counsel Robert Mueller, which was released in redacted form on Thursday.

But the threshold for charging the president might have been breached, had staffers not resisted his directives to engage in actions that would have impeded the investigation.
