Build the wall became one of Donald Trump's defining slogans during his 2016 campaign for president of the United States, chanted repeatedly by supporters at rallies calling for a wall along the border with Mexico. Short clips of the chant were shared widely on social media and in news coverage, turning the phrase into shorthand for his immigration policy. It later spread through memes, reaction videos and political edits, where it is still used to signal support, satire or criticism of border politics.
