POTUS referred to new Presidential powers in his interview today with Chris Wallace that had been bestowed by SCOTUS in what is commonly called the DACA ruling.
The following is what I believe he was exactly what he was referring to.
Under the auspices of today’s decision, administrations can bind their successors by unlawfully adopting significant legal changes through Executive Branch agency memoranda. Even if the agency lacked authority to effectuate the changes, the changes cannot be undone by the same agency in a successor administration unless the successor provides sufficient policy justifications to the satisfaction of this Court. In other words, the majority erroneously holds that the agency is not only permitted, but required, to continue administering unlawful programs that it inherited from a previous administration.
