Republican presidential candidate Donald Trump has said he believes the FBI may have found the "motherlode" of Hillary Clinton's emails.
At a rally in Michigan, he said he hoped the Democratic candidate's 33,000 deleted messages could now be recovered.
Clinton later told a rally she had nothing to hide.
Meanwhile, the acting Chairwoman of the Democratic National Committee Donna Brazile, resigned from her role as a CNN contributor earlier this month.
Her departure was announced yesterday, amid fresh revelations that she sent questions to Hillary Clinton's campaign in advance of a CNN debate and a CNN-TV One town hall.
