Check explaination

Explanation:

With the introduction of Federalism, Government has to be splited into three parts/arms/branches. The three are the executive arm/branch of government, the legislative executive arm/branch of government and the Judicial executive arm/branch of government.

The executive arm of government unlike before now has more power. The article II gives the Executive their powers.

The legislative arm of government was nothing new in the United States of America. The article I of the United States of America gives the legislative the power to make laws and so on. The legislative arm consist of two houses/Chambers. The senate and the house of Representatives.

The Judicial arm of government makes sure the laws that were made by the legislative arm of government are been done.

All the three arms of government helps in keeping each powers at check. The three arms of Government are still working as much as it is working before, we can see that also, during the 'impeachment' of Trump by the house of Representatives and other cases.
