The moment a singer swears on live TV during the National Anthem.

An American singer has apologized after swearing on live TV during the US national anthem.

Loomis drew ridicule on social media after performing “The Star-Spangled Banner” during an independent candidate debate broadcast live on TV station C-SPAN last Wednesday.

On Instagram, she called the incident an “accident” and told the Freedom and Equal Elections team, which organized the debate, “I’m so sorry. I didn’t mean to mess up the national anthem.”
