Conservatives and veterans attacked President Biden for appearing to look at his watch during a ceremony for the 13 U.S. service members killed in an ISIS-K suicide bombing near the Kabul airport in Afghanistan last week. 

Biden met with the families of the troops killed in the attack, and he also attended the "dignified transfer" of the fallen troops, a military ritual of receiving the remains of those killed in foreign combat, while at Dover Air Force Base on Sunday.

During the event, Biden appeared to look down at his watch, sparking criticism from conservatives.

"It's true. Joe Biden checked his watch during the dignified transfer of the servicemembers killing in Afghanistan at the airport. You can see him jerk his left hand to pull the watch out from under his sleeve, then look down at it," Nicholas Fondacaro, a news analyst for the Media Research Center, tweeted with a video.

"Many of us remember Pres Bush 41 checking his watch during a debate and how awful it looked (even though we all felt same way about that debate.) But this is shocking and will be remembered," former Arkansas Gov. Mike Huckabee, a Republican, tweeted with the video.

"Looks like he was being inconvenienced by having to show some respect for these American Heros [sic]," Samuel Williams, an Army veteran who fought in Operation Desert Storm, wrote on Twitter.

"There is nothing more important than paying your respects to America's fallen war heroes, Mr. President," Nile Gardner, a former aide to British Prime Minister Margaret Thatcher and director of The Heritage Foundation's Margaret Thatcher Center for Freedom, wrote on Twitter.

Former White House doctor Ronny Jackson said he was "disgusted" by Biden's appearing to look at his watch.

"Apparently our Commander-in-Chief has better things to do than honor the 13 service members who died on his watch? I’m DISGUSTED! God bless these heroes and their loved ones. They deserved better," Jackson tweeted

"Are you bored, Mr. President?" asked Daniel Gade, an Iraq War veteran and a former Republican nominee for U.S. Senate in Virginia.

Adam Baldwin, an actor best known for his role in the science fiction TV show Firefly (2002), mockingly captioned the video, "Only 10 more minutes until my next dose, right, Jill?"

"He has another meeting," quipped actor Nick Searcy

The White House did not immediately respond to Fox News' request for comment.
