## Step 1<br />The question is asking where all federal spending bills must originate. This is a question about the legislative process in the United States.<br />## Step 2<br />According to the U.S. Constitution, all bills for raising revenue must originate in the House of Representatives. This is because the House of Representatives is the legislative body that is closest to the people, and therefore, it is the most appropriate body to initiate revenue-raising measures.<br />## Step 3<br />The Senate can propose amendments to these bills, but it cannot initiate them. This is to ensure that the legislative process is transparent and that the people's representatives have the final say in matters of taxation and spending.
