Answer :

Any member of the house may introduce a bill by placing it in the hopper of the clerks desk

Answer:

The only people who can introduce a bill in Congress are the members of the house of Representatives.

Explanation:

The members of the house of Representatives are allowed to introduce the bills at any time, but the House must be in session. There are two kinds of bills: private bills and public bills. When they are being introduced to the House they must be established as private bills or public bills because a private bill only influences  a person or any kind of organization, and a public bill concerns the general public.

When a bill is introduced to Congress the Member of this becomes the bill's sponsor. The Representatives usually sponsor some bills, because it would mean that those bills will be useful and important not only for the Representatives but also for their constituents.
