Throughout the presidential campaign, and again at the 2018 CPAC conference, Trump frequently read a song he called "The Snake" to rail against immigrants.
The tale tells the story of a woman who takes in a cold, sick snake and nurses it back to health, only to be fatally bitten.
While he initially used the song to rail against Syrian refugees, by 2018 the president was equating more people with reptiles.
"Think of it in terms of immigration," the president told the CPAC crowd.
"So let's dedicate this to [then–secretary of Homeland Security John] Kelly, the Border Patrol, and the ICE agents for doing such an incredible job," he said at a rally to mark his 100th day in office.
