Vice President Kamala Harris appeared to correct President Joe Biden during his State of the Union address after he mixed up Ukrainians with Iranians.

Toward the end of his remarks on the Russia-Ukraine crisis, Biden slipped a small gaffe, saying “Putin may circle Kyiv with tanks, but he will never gain the hearts and souls of the Iranian people.”

Harris, who was sitting behind him, could be seen mouthing something right after the unfortunate verbal slip-up as she also made a stern face.

It was unclear what the veep said quietly, but eagle-eyed viewers noted she appeared to be mouthing “Ukrainian.”

“LMFAO Kamala appears to mouth ‘Ukrainian’ when Joe Biden said Iranian,” journalist Greg Price said on Twitter.

“Kamala Harris appears to silently correct Biden’s ‘Iranian’ gaffe by mouthing ‘Ukrainian,’” another wrote.

Another Twitter user commented: “Biden doesn’t even know who Russia is invading. ‘Iranian’?? Kamala even looked Embarrassed and mouthed ‘Ukrainian…’”

Harris was mocked herself earlier for an appearance on the syndicated “Morning Hustle” radio program, where she was asked to explain the conflict “in layman’s terms for people who don’t understand what’s going on and how can this directly affect the people of the United States?”

Speaking slowly, Harris said, “So, Ukraine is a country in Europe.”

“It exists next to another country called Russia,” she continued. “Russia is a bigger country. Russia is a powerful country. Russia decided to invade a smaller country called Ukraine. So, basically, that’s wrong, and it goes against everything that we stand for.”
