However, trying to help you we did some deep research and can comment on the following.
What explains how the legislative branch can check the power of executive and judicial branches is the following.
The Legislative branch can check the power of the executive and judicial branches in that it can impeach the President of the United States and it can refuse to approve Supreme Court nominees.
That is why the American founding fathers created the system of checks and balances when they chose the division of powers for the federal government in three different branches, so none of the three branches could have more power over the other two. This was part of the negotiations during the Constitutional Convention of Philadelphia, Pennsylvania in 1787 between Federalists and Antifederalists.
In this particular case, the Legislative branch that is the upper chamber or Senate, and the lower chamber or House of Representatives, have powers over the other two, and of course, the judicial and the executive have powers over the legislative.
