Answer:
Amendment starts in Congress.
Explanation:
The process of amendment of the constitution may begin when;
The U.S. legislature form a two-thirds majority in both the Senate and the House of Representatives (congress) in favor of the proposed constitutional amendment;
Or
A national convention is called by Congress for for the purpose of constitutional amendment, when the legislatures of two-thirds of the states apply for the commencement of a constitutional amendment process.
The president signs the amendment into law at the end of the process. 3/4 of the states*about 38 out of 50 states) must approve the constitutional amendment.
We can see that constitutional amendment must not necessarily start in congress as explained above.
