On Saturday, President Donald Trump cited the city of San Antonio as a place where a border wall has been effective.

The problem: The central Texas city is more than 150 miles from the closest border crossing and, as such, has no wall.

Trump cites San Antonio as an example of a city where a border wall has worked. It’s located 150 miles north of Mexico and there is no wall. pic.twitter.com/CyiOiGuCy3

Trump’s geography mistake was pounced on by proud Texans who brutally mocked the president’s error online and in Texas media.

Here are some of the best tweets on the subject.

You know San Antonio home of the Spurs, the Riverwalk, the Alamo and the Great Wall of San Antonio pic.twitter.com/cJzgU1THQC

#TBT I bet he said San Antonio because that is the one city he knows which sounds Latino enough to be close to Mexico. He is going to cite Dos Equis or Corona next because that is a lot easier #realtalk #NotMyPresident
