What power enables the president to reject a bill passed by the legislature

The Framers of the Constitution gave the President the power to veto acts of Congress to prevent the legislative branch from becoming too powerful. The veto allows the President to “check” the legislature by reviewing acts passed by Congress and blocking measures he finds unconstitutional, unjust, or unwise. 

Hope this helps :)
