Independent analyses, ranging from Yale University to the Wharton School to the Congressional Budget Office, have each said that President Trump’s Big Beautiful Bill will add trillions of dollars to the U.S. deficit over the next 10 years.

In this documentary, through dozens of interviews with experts including Former Treasury Secretary Robert Rubin, macro investor Ray Dalio and Former Chairman of the Joint Chiefs of Staff Mike Mullen, CNBC’s Leslie Picker explores what will happen if the deficit is not reined in.
