Michelle Obama described Barack Obama's work ethic as "tireless", but he only worked 4 hours per day in May

Michelle Obama is worried Barack Obama is working too hard.

"I see the sadness and worry that's creasing his face," she said to a crowd of about 500 at the Pasadena luncheon organized by the Southern California Women For Obama. She described his worth ethic as “tireless,” according to pool reports.

"He reads every word, every memo, so he is better prepared than the people briefing him," she said. "This man doesn't take a day off."

According to President Obama's official schedule, he only worked 4 hours per day in May and that includes the time he spent attending awards banquets.

At the President's press conference today, Mr. Obama made frequent references about the Congresses need to "do its job." He also implied that he was hard at work, in Washington and the Congress should be too. An analysis of Mr. Obama's published work schedule raises some questions about the actual level of presidential exertion.

According to the White House, the President doesn't work all that much. During the month of May, which included 21 working days, President Obama claims he worked about 92 hours (91.95 to be exact). That's according to the White House schedule, posted on the whitehouse.gov Website. That equates to an exhausting 4.4 hours per day. Excluding his grueling G8 summit travels during the week of May 23 (when he was forced to endure eight hour work days!), Mr. Obama worked an average of 3.25 hours per day when at the White House in May.

Indeed, the President's schedule is so thin, the White House Communications team sees it necessary to include the Vice President's meetings, when he subs for the President* for padding. For example, on May 3rd and May 17th, Vice President Biden held working breakfast meetings at 7:45 am with Secretary of State Hillary Clinton and Treasury Secretary Timothy Geithner in the President's stead.

Michelle Obama must think golfing is work.
