 Joe Biden has insisted that he won't withdraw from the US presidential race despite appeals from a growing number of fellow Democrats. Mr Biden, who's 81, said he would not be pushed out of November's election. Democratic Party governors who met Mr Biden at the White House said they'd pledge their support. Lindy Lee, who is going to be one of the delegates at a meeting of the Democratic National Convention next month, says the party faces a difficult but crucial decision whether to replace Joe Biden.
