The White House says President Trump signed an executive order declaring a national emergency to protect the bulk-power system from foreign interference, framed as a supply-chain security measure.
The release describes goals of eliminating vulnerabilities and ensuring reliable electricity, but offers no specifics on which foreign actors, which equipment, or what enforcement mechanism follows the declaration.
As with prior fact sheets from this office, the self-description of the policy is the only account given, and the White House is the sole source quoted throughout.
The full dispatch is available from the source below.
