Barack Obama has denounced Senate delays in passing his economic stimulus package as “irresponsible” and “inexcusable.”The US President hardened his tone at the White House on the day new jobless figures made alarming reading. ¨We have lost 3.6 million jobs since this recession began – that is 3.6 million Americans who wake up every day wondering how they are going to pay their bills, stay in their homes and provide for their children. That is 3.6 million Americans who need our help,” said Obama, as he named a new economic panel to help guide his efforts. “I am sure that at the other end of Pennsylvania Avenue, members of the Senate are reading these same numbers this morning and I hope they share my sense of urgency and draw the same unmistakable conclusion – the situation could not be more serious.” Obama says his bill, equivalent to around 700 billion euros, would help in the short term as well as furthering long term goals such as improving infrastructure. But Republicans have taken aim at spending provisions such as money to promote the arts which they say would do little to get America back on its feet.
