The Pennsylvania senator dismissed the demand for further investigation as “moot.”

Senator John Fetterman appeared not to understand why Democrats want to investigate the deadly strike that killed dozens of Iranian children.

During an interview with CNN’s Kaitlan Collins Wednesday night, Fetterman was asked to explain why he hadn’t signed onto a letter from Senate Democrats that questioned Defense Secretary Pete Hegseth on the February 28 strike on Shajarah Tayyebeh, a girls’ primary school miles from Tehran. The strike killed 175 people, many of them young girls.

“Well, because we all agree that it’s a tragedy having the school hit, and we all agree now for an investigation,” Fetterman said. “What I don’t agree with the rest of my colleagues in the House is that it’s a war of choice, or it’s dumb, or all the things my colleagues have described, you know, this operation. I think it’s a good thing, and I support that.”

Fetterman was referring to a line in the letter describing Donald Trump’s military campaign as “a war of choice without Congressional authorization.” The letter did not describe the war as “dumb.”
