Sen. John McCain, his wife and a dependent child incurred charge and credit card balances of at least $225,000 in 2007, according to senate financial disclosure documents filed by May 15 and released Friday. Cindy McCain logged balances between $100,001 and $250,000 each on two American Express charge cards in 2007. Both cards carry 0% interest rates, as does another AmEx charge card listed in McCain's disclosure form as belonging to a dependent child. The child's card hit a balance of between $15,001 and $50,000 during 2007. The couple logged a high balance of between $10,001 and $15,000 on a joint "charge card" issued by JPMorgan Chase & Co. The card's annual percentage interest rate is 25.99%. Sen. Barack Obama reported no financial liabilities on his annual financial disclosure form. Senate leaders, including committee chairmen and ranking committee members, must file the disclosures each year, as do some senators the Senate is investigating for possible ethics violations. The records provide a snapshot of personal assets and liabilities that those senators, their spouses and dependent children carried at any time last year, debts which may or may not have been carried over into 2008, staff of the Senate Public Records Office confirmed yesterday for CardLine. The forms instruct senators to check boxes next to ranges of the highest debt owed to each creditor listed during 2007, instead of writing in precise amounts.
