The US Secret Service is to boost protection for Joe Biden from Friday in anticipation that he might soon claim victory in the elections, said the Washington Post.
Extra agents have been put in place after his campaign team told Secret Service that he could make a major speech as early as Friday.
Secret Service spokesperson Catherine Milhoan declined to comment, saying that the agency did not discuss security arrangements for senior figures. Biden aides have also refused to comment.
Democratic presidential hopeful, Biden, and his team have been based at a convention centre in Wilmington, Delaware.
