Vermont Sen. Bernard Sanders on Sunday accused Hillary Clinton of being too quick to rush to war, and said the former secretary of state’s supporter for the Iraq war was not merely an isolated incident but instead one example in a clear pattern.

The Democratic presidential candidate was asked on CNN’s “State of the Union” if he worries that Mrs. Clinton could push the U.S. into war if she’s elected.

“I worry about that, yeah, I do,” he said. “I think her support for the war in Iraq was not just an aberration. I think her willingness to kind of push President Obama to overthrow [Moammar] Gaddafi and lead to the kind of instability that we’re seeing now in Libya, not inconsistent with her other views in Syria, where she wants a no-fly zone which could suck is into never-ending conflict in that area.”

Mr. Sanders was an outspoken opponent of the Iraq conflict, while Mrs. Clinton voted to approve the war in 2002. She has since said the war was a mistake.

Last week, the former first lady said presumptive Republican presidential nominee Donald Trump would lead the U.S. into war because of his poor temperament. Mr. Trump responded by criticizing Mrs. Clinton’s Iraq war vote in 2002.

Watching from the sidelines, Mr. Sanders took shots at both candidates.

“Frankly, I think they both make a point,” he said.
