Brief Explanations:

According to Article V of the U.S. Constitution, amendments can be proposed in two ways: either by a two - thirds vote in both houses of Congress (the legislative branch) or by a constitutional convention called by two - thirds of the state legislatures. The president, vice - president, and the Supreme Court do not have the sole power to propose constitutional amendments. The president's role is mainly in the executive branch, and the Supreme Court is in the judicial branch. Their powers are separate from the amendment - proposing power which lies with Congress (as part of the legislative process at the federal level) and state legislatures (as a state - level legislative power in the amendment - proposing process).

Answer:

Congress and state legislatures.
