U.S. President Donald Trump shot back at British Prime Minister Theresa May Wednesday night, telling her to focus on her own country rather than criticize him after posted by the leader of a far-right group in the United Kingdom.

Blasting political foes on Twitter isn鈥檛 unusual for the U.S. president. But this tweet was exceptional for a rudimentary reason: Trump tweeted at the wrong person.

The British prime minister鈥檚 verified Twitter account, has more than 418,000 followers and is open to the public. The account Trump tweeted at, is a private account belonging to Theresa Scrivener. Scrivener has six followers.

It didn鈥檛 take long for Trump to notice the mix-up, and he deleted the tweet just before 8 p.m. EST. He replaced it with the British leader鈥檚 proper Twitter handle.

In his Trump told May, 鈥渄on鈥檛 focus on me, focus on the destructive Radical Islamic Terrorism that is taking place within the United Kingdom. We are doing just fine!鈥�

Trump鈥檚 comment comes after May slammed the president鈥檚 behaviour in a statement, saying, 鈥淚t is wrong for the president to have done this.鈥�

In her own tweet Wednesday, May said her country is 鈥渃ommitted not only to defeating Daesh militarily but also to countering the dispersal of foreign fighters from Iraq and Syria.鈥�
