Charles Pinckney worked with a Congressional Committee to draft amendments for the Articles of Confederation.

Explanation:

Charles Pinckney was an American politician. He was one of the signatories of the American constitution and held various political positions. He was, for example, Governor of South Carolina and a member of the House of Representatives and the Senate.

Pinckney's role in the Constitutional Convention, where the Constitution was drafted, is considerable. He came up with a very detailed proposal, a precursor to the Virginia Plan, but this was ignored by the other members. In it, he instituted the introduction of a two-chamber system, in which the states had proportional representation in one Chamber and the composition of the other Chamber was based on population. After the Convention, Pinckney played an active role in the ratification of the constitution by South Carolina.  

During the Convention, Pinckney and Pierce Butler, also from South Carolina, introduced a proposal that states should pick up fled slaves and return them to their original owners. The amendment was adopted and was not put into effect until 1864, during the Civil War.
