The Republican candidate's daughter and son allegedly earned 84,000 euros ($91,000) from 2005 to 2007 while working for him when he was a Senator, Le Canard Enchaine said. His wife, Penelope Fillon, earned more than 900,000 euros during over a decade as a parliamentary assistant and a contributor to a magazine while doing little actual work, according to Le Canard.

The newspaper's initial report on Penelope's job last week triggered a prosecutor to open a preliminary probe into the family's affairs. It's not illegal to hire relatives for public posts in France, so long as they perform their duties. The candidate says he's innocent.
