Newsweek is set to publish a highly embarrassing report on Sen. John McCain, revealing that the McCains have failed to pay taxes on their beach-front condo in La Jolla, California, for the last four years and are currently in default

Under California law, once a residential property is in default for five years, it can be sold at a tax sale to recover the unpaid taxes for the taxpayers.

The McCains own at least seven homes through a variety of trusts and corporations controlled by Cindy McCain.

UPDATE: Newsweek's story is now online. The report notes that the McCains paid the bulk of their back taxes yesterday, but continue to owe additional taxes:

Shortly after NEWSWEEK inquired about the matter, the McCain aide e-mailed a receipt dated Friday, June 27, confirming payment by the trust to San Diego County in the amount of $6,744.42. County officials say the trust still owes an additional $1,742 for this year, an amount that is overdue and will go into default July 1
