A video shows that Donald Trump made a false claim about the lack of deaths in Afghanistan during his presidency.

The former president took to the stage in Austin, Texas, shortly after an 18-year-old opened fire at a supermarket in Buffalo, New York, killing 10 people.

I think there was a tragic event in Buffalo, just as I was about to speak, with many people being killed, Trump said in the video.

In 18 months in Afghanistan, we lost nobody, according to the former president. He talked about negotiating with the co- founder of the Taliban.

During his presidency, Trump claimed that nobody died in Afghanistan.

It is not clear which 18-month period Trump was referring to. The Insider reached out to the post-presidency office for clarification.

He may have been referring to claims popularized on social media, in which Trump supporters said there were no US military deaths between February 2020 and August 2021. These claims are not true according to a USA TODAY fact check.

According to USA Today, there were four US deaths in Afghanistan, but not in combat situations. President Joe Biden was in office for eight of those months.

If Trump was referring to the last 18 months of his presidency, it's incorrect.

There were 11 military deaths in Afghanistan in 2020. There were 22 US service members who died in Afghanistan during the final 18 months of Trump's presidency.

Ted Lieu of California criticized Trump on Saturday night.

Lieu, an Air Force Reserve Command colonel, wrote that this is a ridiculous comparison by the former President.
