The government of the United States is divided into three branches: executive, judicial, and legislative. Federal laws require either the agreement of the legislative and executive branches, or overwhelming support within the legislative branch alone. (A president can sign a bill passed by both houses of congress or he can veto it. A veto can be overridden by a two-thirds vote in each chamber of congress.)<p>Therefore, petitioning the White House for a law is ineffective and reflects a lack of understanding of constitutional government in the United States. Instead, try contacting your congressional representative or one of your senators.
