The board does not have any operational authority or capability. What it will do is gather together best practices in addressing the threat of disinformation from foreign state adversaries, from the cartels, and disseminate those best practices to the operators that have been executing in addressing this threat for years.

Almost all of the initial reporting on the DGB lacked any specifics of what concrete powers the group will exercise to “counter,” “combat,” and “crackdown on” so-called disinformation.
