Republican voters flatlined after President Biden claimed that no troops have died under his watch – failing to acknowledge the service men and women who have died during his administration.

During a Fox News Digital focus group, Republicans, Democrats and Independents used dials to react live to President Biden's claim during the presidential debate that no troops died under his watch.

"When he was president, they were still killing people in Afghanistan," Biden said, referring to former President Donald Trump. "And he didn't do anything about that."

"When he was president, we were finding ourselves in a position where you had a notion that we were this safe country," Biden said. "The truth is, I'm the only president this century, this decade, that doesn't have any troops dying anywhere in the world like he did."
