Sources close to the White House say Mr Obama and his staff have been "overwhelmed" by the economic meltdown and have voiced concerns that the new president is not getting enough rest.
But Washington figures with access to Mr Obama's inner circle explained the slight by saying that those high up in the administration have had little time to deal with international matters, let alone the diplomatic niceties of the special relationship.
Allies of Mr Obama say his weary appearance in the Oval Office with Mr Brown illustrates the strain he is now under, and the president's surprise at the sheer volume of business that crosses his desk.
A well-connected Washington figure, who is close to members of Mr Obama's inner circle, expressed concern that Mr Obama had failed so far to "even fake an interest in foreign policy".
...The Sunday Telegraph understands that one of Mr Obama's most prominent African American backers, whose endorsement he spent two years cultivating, has told friends that he detects a weakness in Mr Obama's character.
"The one real serious flaw I see in Barack Obama is that he thinks he can manage all this," the well-known figure told a Washington official, who spoke to this newspaper. "He's underestimating the flood of things that will hit his desk." A Democratic strategist, who is friends with several senior White House aides, revealed that the president has regularly appeared worn out and drawn during evening work sessions with senior staff in the West Wing and has been forced to make decisions more quickly than he is comfortable.
