When the President starts making emergency declarations, he in essence lifts the Executive Branch above the other 2 branches to streamline debate and decisions (protect the Nation).
Right now by virtue of the National Emergency, President Trump is, by law and by the design of the Constitution, ABOVE the other 2 branches for the duration of the emergency.
Nancy can no longer stop President Trump. He doesn't need passed bills anymore. He can allocate from the US Treasury by decree now.
It was over when President Trump took the oath of office.
