Reporting live from Prague, Stephanopoulos was mostly light on details. He did explain that the treaty's goal is to cut "nuclear arsenals by about 30 percent over the next seven years." And while the ex-Democratic aide allowed that "critics call [the treaty] utopian and dangerous," he didn't explain why.
Co-host Robin Roberts announced, "George Stephanopoulos is there in Prague for the historic moment." She later teased, "George is traveling, of course, with the President, who just signed a landmark treaty."
