The EO does not order legislation. It orders:
"Sec. 6. Bill Text. Within 30 days of the date of this order, the Assistant to the President for Legislative Affairs shall present to the President proposed bill text to codify the definitions in this order."
Once he has the proper bill text, he can present it to any of his cronies and they can write the bill and submit it to become law.
