It was also almost word-for-word the same as the tweet he had posted about the Sutherland Springs shooting shortly after it happened.
However, Twitter users immediately pointed out the glaring mistake and tore into Trump accusing the president of using "copy and paste" to post his first message addressing the latest USA shooting.
The tragic shooting in Sutherland Springs, Texas has changed our way of thinking.
"May God be with the people of Sutherland Springs, Texas".
Even TV presenter Piers Morgan, a friend of the United States leader, tweeted Trump to point out his error.
Twitter users questioned the timing of the tweet and wondered if Trump accidentally sent out a saved draft. Others were left baffled by the confusion.
The commander-in-chief failed to recognize the latest massacre in Rancho Tehama Reserve, California, on Tuesday morning when a lone gunman occurred went on a random shooting spree in around the tiny community and targeted the local elementary school.
This led to many claims that the president had been "copying and pasting" his tweets. 26 people were killed after a man started shooting on November 5th at a Sunday service. Another added: "Did you reuse this tweet for the last mass shooting?"
Piers Morgan, a supporter of Mr Trump, said: "At least get your mass shootings right, Mr President".
Twitter users were quick to slam Trump after the Tweet, which still remained on his twitter feed a day after it was posted.
