good morning to you. thank you for being with us. 6:00 a.m. in new york this morning. tuesday, july 19th. i was hearing that in parts of iowa the heat index felt like 130 yesterday. it s been brutal out there. even this morning on the east coast, it felt different. it felt hotter. we ll be covering that. we re watching that and millions are watching with a worldwide media empire hanging in the balance rupert murdoch is just hours away from facing his defining moment. in less than four hours, murdoch, his son and former top newspaper executive will appear before the british parliament. they will be asked what they knew about this phone hacking scandal that s growing wider by the day. it s threatening to take down news corp and perhaps murdoch himself. and the question is what they are going to be called upon to explain, what they re going to be compelled to explain and how that s different from being called before congress. who is going to be asking the questions today
