CNN, MSNBC, ABC, and CBS all aired a silent commemoration of the first plane striking New York's World Trade Center 11 years ago, as President Barack Obama and the first lady led the moment of remembrance at the White House.
Meanwhile, NBC's "Today" show's host Savannah Guthrie was speaking with Kris Jenner, the mother of reality star Kim Kardashian, about her first breast implant surgery in 23 years.
Irate viewers soon flooded Twitter to voice their outrage and shock that NBC did not show the annual commemorative moment of silence.
"NBC didn't take a moment of silence today for 9/11 at 8:46 this morning, because they were interviewing Kim Kardashian. #Disrespectful," wrote @Caseyacord13.
Another user wrote, "The fact that Kris Jenner is a guest on the today show on 9/11 seriously makes me doubt humanity."
"Another reason not to watch @NBC "@MarkRaganCEO: 'Today' show airs Kardashian interview over 9/11 remembrance," tweeted @marciehunter.
Megan Kopf, a "Today" spokeswoman, defended the network's coverage of the 9/11 anniversary ceremony.
"The Today show dedicated a considerable amount of time to Sept. 11 coverage this morning throughout the entire show," Kopf told Politico.
