Lawmakers are getting feisty ("IS PAULSON LYING?" "IS KEN LEWIS LYING?"), but Professor Bernanke seems to be keeping his cool on the Hill this morning, where he's being questioned about the alleged threats he and Henry Paulson made last year to prevent Bank of America CEO Ken Lewis from backing out of the deal to acquire Merrill Lynch. “The Federal Reserve acted with the highest integrity throughout the discussions with Bank of America regarding that company’s acquisition of Merrill Lynch,” he said in his prepared statement. "I have nothing I regret about the whole transaction.” DealBook is live-blogging and the House Oversight Committee is streaming it, if you want to watch Darrell "It's all a cover-up!" Issa's veins pop out of his neck in real time.
