A U.S. judge on Monday heard arguments for and against Visa's and Mastercard's  revised $38 billion settlement with merchants who accused the card networks of charging too much to process payments on their credit cards. U.S. District Judge Brian Cogan in ​Brooklyn, New York, didn't say whether he would grant preliminary approval, but said, during a nearly three-hour hearing, he ‌wasn't looking to use a "meat cleaver" to dismantle the credit card process for card networks, banks, merchants and consumers.
