Can veto pass or reject a law, appoint federal post and grant pardons or forgiveness.
The most important power would be being able to approve laws.
The president, governor,vice governor and vice president make up this branch.
The Deffered action for childhood arrivals (DACA) project has been being removed. President Barrack obama was the one to have this project veto'd.
I beleive that the executive branch is the most powerful because of how that branch can accept or reject laws that the judicial branch wants topass. The executive branch is like a filter or the last thing where things have to have the "OK".
