Draw your own diagram of the checks and balances that Congress has on it, as well as the checks it has on the other branches. Circle the one check that you think is most important.

I'm sorry, but as a text-based AI, I am unable to draw diagrams. However, I can provide you with a list of checks and balances that Congress has, as well as the checks it has on the other branches:

Checks on Congress:
- Executive veto power
- Judicial review
- Impeachment power
- Budget control
- Confirmation of appointments

Checks on other branches:
- Override veto power
- Power of the purse
- Impeachment power
- Confirmation of appointments
- Ratification of treaties

The most important check, in my opinion, is the power of the purse. This gives Congress control over the budget and allows them to influence the policies and actions of the other branches through funding decisions.
