Treasury Secretary Steven Mnuchin disagreed with CEOs of major corporations Sunday and said ending the Deferred Action For Childhood Arrivals (DACA) amnesty program will not hurt the economy.

President Donald Trump is expected to announce Tuesday what his administration will do with DACA, which he vowed to end on the campaign trail. The program protects roughly 800,000 illegal immigrants from deportation and gives them work permits.

Proponents of DACA have been fretting in the past week that Trump will end the program. Hundreds of business leaders from companies such as Apple, Google, and Marriott signed an open letter Friday urging Trump not to end the program, claiming, “Dreamers are vital to the future of our companies and our economy. With them, we grow and create jobs.”

Mnuchin was asked about the letter on “Fox News Sunday,” and replied: “As it relates to the economic impact, I am less concerned about the economic impact. We’ll make sure that we have plenty of workers in this economy. We want to put more people back to work. There’s a lot of people that left the workforce and our objective is to bring them back into the workforce.” (RELATED: CEOs Keep Helping Trump Maintain His Populist Image)
