How is legislative power divided in the congress?

In the U.S. Congress, legislative power is divided between two chambers: the House of Representatives and the Senate. The House, with its larger membership, focuses on more direct representation of the populace and has the exclusive power to initiate revenue bills. The Senate, with its smaller membership, represents states and has unique powers, such as confirming presidential appointments and ratifying treaties. This bicameral structure ensures a balance of power and a system of checks and balances within the legislative process.
