Good morning, NBC News readers.

"Star Wars" fans are mourning the loss of Peter Mayhew, the actor best known for playing the beloved Chewbacca in the iconic film series.

Here's what else we're watching today.

'He lied to Congress'

House Speaker Nancy Pelosi, D-Calif., did not mince words Thursday about her views on Attorney General William Barr's testimony before Congress last month.

"The attorney general of the United States of America was not telling the truth to the Congress of the United States. That's a crime," Pelosi told reporters Thursday.

She was referring to testimony Barr gave to Congress in April in which he denied knowledge of the Mueller team's concerns.

"Nobody is above the law — not the president of the United States, not the attorney general," Pelosi added.

'Run, hide, fight' mantra put into practice during shooting at UNC Charlotte

When reports of a shooter spread on the campus of the University of North Carolina at Charlotte on Tuesday, the college's emergency officials blasted out a stark, but increasingly familiar message: "Run, hide, fight."

Having no place to run or hide, one student, Riley Howell, took the last option and confronted the gunman.

His actions "took the assailant off his feet," Charlotte-Mecklenburg Police Chief Kerr Putney said. "But for his work, the assailant may not have been disarmed. Unfortunately, he gave his life in the process, but his sacrifice saved lives."

While Howell's family is grappling with his death, they said they are "beyond proud" of his actions.

'So long, Chewie, may the force be with you'

Peter Mayhew, who roared inarticulately yet somehow understandably as Chewbacca for generations of "Star Wars" fans, has died at age 74.

Mayhew towered — literally at over 7 feet tall — as the 200-year-old Wookiee from the planet Kashyyyk who co-piloted Han Solo's Millennium Falcon.

Tributes poured in for the man who was hailed as both a gifted actor and a gentle giant.

"We all love Chewie, and have Peter to thank for that enduring memory," said Kathleen Kennedy, president of Lucasfilm, the Disney-owned studio behind "Star Wars."

White House officials are weighing whether to designate the Muslim Brotherhood a foreign terrorist organization — a move experts warn would make the United States less safe and end up victimizing American Muslims to curry favor with authoritarian allies.

"A real concern here is this designation is also a smokescreen to essentially attack the American Muslim community through guilt by association," one expert said.
