Leaders from five continents are in Venezuela to attend the funeral of President Hugo Chavez on Friday.
The ceremony will mark a dramatic exit for a president who quarreled publicly with presidents and kings and ordered troops via live television to defend his country’s borders.
Representing the United States will be Congressman Gregory Meeks of New York and former Congressman William Delahunt of Massachusetts. Both are Democrats.
Chavez often portrayed the United States as a great global evil.
