The Geographic map of the 50 US states is color-coded to show the number of arrests in regions along the US-Mexico border. Out of a total of approximately 150K total federal arrests, nearly 60% were concentrated along the US southern border. In 2019, Trump tweeted that 23% of federal inmates are undocumented immigrants.
It is clear that federal resources are being dedicated to arrests along the US-Mexico border and to feeding/housing undocumented immigrants inmates. However, the positions of both major political parties oppose Trump’s obsession with installing an expensive climbing apparatus along Mexico.
