What check does the president have over congress?

rejecting candidates for the supreme court overriding a veto using a veto declaring laws unconstitutional

The choices for this question are:

A) rejecting candidates for the Supreme Court

B) overriding a veto

C) using a veto

D) declaring laws unconstitutional

The correct answer is C.

A is wrong because the Supreme Court belongs to the judiciary branch. B is wrong because the president does not have that power, only Congress does. D is wrong because that is the check the judiciary has over Congress.

C is correct because that's how the president checks Congress power: it can use his/her power to veto a bill he/she believes it's bad for the nation. And Congress, on the other hand, can override the veto. That's how part of the checks and balances between Executive and Legislative works.
