US President Joe Biden, in a slip of tongue, referred to Ukrainians as “Iranians” in his State of the Union speech. He was making an impassioned appeal for people to put up a united front against Russian aggression and stand in support of Ukraine.

His gaffe, however, soon went viral on social media platforms, reports ANI. “Putin may circle Kyiv with tanks, but he’ll never gain the hearts and souls of the Iranian people,” Biden can be heard saying in a viral clip of the incident. Vice President Kamala Harris can be seen standing next to him.

Some Twitter users have claimed that Harris seems to mouth “Ukrainian” just as Biden makes the mistake in his speech.
