Barack Obama has urged lawmakers to resolve their differences and reach agreement over a stimulus package for the economy. A fourth day of deliberations takes place in Congress today. The US president has indicated he might be prepared to see the plan trimmed by around 100 billion dollars to just over 800 billion dollars: “The time for talk is over. The time for action is now, because we know that if we do no act, a bad situation will become dramatically worse. Crisis could turn into catastrophe for families and businesses across the country. And I refuse to let that happen,” said Obama.
