MEXICO CITY (Reuters) - The United States is still hammering out a final guest list ahead of next week's Summit of the Americas in Los Angeles, senior U.S. officials said on Wednesday, after weeks of tension around several countries expected to be excluded.

Summit preparations have been clouded by the threat of an embarrassing boycott by some regional leaders, including Mexican President Andres Manuel Lopez Obrador, if Cuba, Venezuela and Nicaragua are not invited.
