Sens. Barack Obama and Hillary Rodham Clinton showered each other with praise yesterday in their first joint appearance since the end of the Democratic presidential primary season at an event in which the senator from New York urged hundreds of her top donors to get behind the party's presumptive nominee.

Bill Richardson, the governor of New Mexico, a former US presidential candidate and a current key figure in the campaign backing Barack Obama, the Democratic candidate for this year's presidential elections, was in Cairo this week in an advanced attempt to promote Obama as a US president with a will to fortify good relations with the region, including Egypt, which he described as a country with a pivotal role for the stability of the Middle East.
