First lady Michelle Obama on Monday told a fundraiser in Southern California of the toll the presidency has taken on her husband Barack Obama.

"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."

She said the next two years of campaigning would be difficult for the Obamas and their supporters. "It is not going to be easy, and it is going to be long," she said. "Now more than ever we need your help to finish what we started."

She also mentioned health care reform, the passage of the Lilly Ledbetter Act and the repeal of Don't Ask, Don't Tell. She praised "justice" in the killing of Osama bin Laden, and the withdrawal of troops from overseas.

Guests paid $1,000 per ticket to attend the event. This evening, she will speak at another fundraiser in Westwood.
