Trump sent DACA and the Iran deal back to Congress to be legislated.  They were done by Obama unilaterally..  The Iran “deal” thru the UN should have required a 2/3rds vote of the Senate. The $7BB sent to the insurance companies as subsidies was pulled by Obama straight from the Treasury and not appropriated by Congress.  Obama acted way more Imperial that Trump has so far.  Imagine Trump pulling funds to pay for the border wall straight from the Treasury without Congressional approval.  How is Trump acting like an Emperor when he puts the legislative function back with Congress where it belongs.
