Cindy McCain has released her 2006 tax returns, showing total income of more than $6 million. The wife of Republican presidential candidate John McCain paid more than $1.7 million in taxes.
McCain's campaign said she had received an extension on her 2007 tax returns and planned to make those public when they are filed.
Under a prenuptial agreement, the McCains have separate assets and file separate tax returns. John McCain made his tax returns public last month.
McCain's campaign only released the top two summary pages of Cindy McCain's 2006 return. In them, she listed itemized deductions totaling nearly $570,000. Mrs. McCain is the heiress of a large Arizona beer distributorship.
