Kelly Clarkson said she was supposed to lead a moment of silence on Sunday night as she hosted the Billboard Music Awards in the aftermath of yet another school shooting — this one at Santa Fe High School in Texas, which killed 10 people.

But she had something else in mind.

“I’m so sick of moments of silence,” Ms. Clarkson said, as she fought through tears. “It’s not working, like, obviously.”

She continued: “So why don’t we not do a moment of silence? Why don’t we do a moment of action? Why don’t we do a moment of change? Why don’t we change what’s happening? Because it’s horrible.”

She didn’t mention exactly what action she meant, nor did she specify that she was in favor of limiting access to guns. But it was a notable statement. Ms. Clarkson is a gun owner herself and has spoken publicly about it several times. She told NPR in 2012 that she owned nine guns and that she slept with a Colt .45.
