Former President Donald Trump and Florida Gov. Ron DeSantis make tough promises on immigration.

Trump vows to end on his first day in office the right to citizenship for the children of migrants born in the U.S. Florida's governor charges against'sanctuary' cities and says he will declare a state of emergency at the border. None of these claims were backed up with data, nor is there any clear indication that they are true, even though they are clear Trump supporters. The two men are the Republican candidates with the most support in the polls.
