through the president's rejection of laws

through the declaration of laws as unconstitutional

Explanation:

The US government is based on the principle of Separation of Powers which sets the basis for the Checks and Balances system. Under this latter, each of the three branches has the power to oversee, check and limit the other branches. Two ways in which the Legislative branch powers are held in check are the following:

1. Through the president's rejection of laws: Congress has the power to create and pass bills, however, these bills can not become laws until they are sent to the President who has the power to sign them into laws, to reject them (in which case, they are sent back to Congress) or to sit on them.

2. Through the declaration of laws as unconstitutional: The Supreme Court has the power to evaluate laws and to determine the constitutionality of laws passed by Congress and acts of the executive. If the Supreme Court declares a law passed by Congress unconstitutional, it is rendered invalid.
