How is the president involved in the process of bills becoming laws?

Decides if its right and signs the papers, or vetoing it/making amendments

Steps in how the law-making process goes. first a bill may begin in either the House or the Senate except for money bills, which must be introduced in the House. second a  Bill is Drafted = Members of Congress, the Executive Branch, and even outside groups can either draft, write or draw up bills. hope this helps and please rate below :)
