Who is a lobbyist?

Since the founding of the American Republic, Lobbyists have been an intrinsic part of the democratic process of governance. In simple words, a lobbyist is an activist who works to convince members of the Congress to ordain legislation that benefits the group or cause that he/she supports. A lobbyist could be a paid professional or even a volunteer. The lobbying profession is very much legitimate and is fundamental to the U.S. representative system. It is recognised under the 1st Amendment of the U.S. Constitution.
