The immigration debate dominated Trump's address, with Trump defending his administration's stance on the Deferred Action for Childhood Arrivals (DACA) program, which protects immigrants brought to the U.S. illegally as children from deportation.

Trump gained praise from supporters and ire from critics when he declared that "Americans are dreamers too," in a reference to DACA recipients.
