Chicago Mayor Rahm Emanuel [official website] delivered a letter [PDF] to US President-elect Donald Trump Wednesday signed by many US mayors warning of the potential economic losses Trump could cause if he repeals Deferred Action for Childhood Arrivals (DACA) [official website]. DACA allows undocumented young immigrants to remain in the US if they arrived before they turned 16 and are currently working, pursuing higher education or serving in the military. The letter, which was signed by the Mayors of New York City, Los Angeles and San Francisco among others, warned [press release] that repealing DACA could result in a loss of $9.9 billion in tax revenue over four years and $433.4 billion in US gross domestic product over 10 years. Emanuel wrote:

Ensuring DREAMers can continue to live and work in their communities without fear of deportation is the foundation of sound, responsible immigration policy. Ending DACA would disrupt the lives of close to one million young people, and it would disrupt the sectors of the American economy, as well as our national security and public safety, to which they contribute. We encourage your Administration to demonstrate your commitment to the American economy and our security by continuing DACA until Congress modernizes our immigration system and provides a more permanent form of relief for these individuals.
