Questions over Clintons' earnings

Washington: New questions are being raised about the earnings of former president Bill Clinton and his wife Hillary after revelations they earned $109 million in eight years.

The concerns come as analysts focused on $52 million that Bill Clinton has earned for public speaking, a day after Hillary posted financial documents, including tax returns, on her website.

Some observers are linking Bill Clinton's earnings to donations made to Hillary's Democratic presidential nomination campaign.

The disclosure follows weeks of pressure by the camp of rival candidate Barak Obama to match his publishing of tax returns.
