Michelle Obama:My husband will be 'extraordinary president'

DENVER, Colorado (CNN) - Michelle Obama took center stage at the Democratic National Convention on Monday night, stressing her love for the nation and making her case for why her husband should be the next president.

"I come here as a wife who loves my husband and believes he will be an extraordinary president," she said of her husband, Sen. Barack Obama of Illinois, the presumptive Democratic nominee.

Michelle Obama - who could be the nation's first African-American first lady - pushed a theme of unity in light of controversial comments she made on the campaign trail that raised doubts about her patriotism.

"All of us are driven by a simple belief that the world as it is just won't do - that we have an obligation to fight for the world as it should be," she said, closing the first night of the convention.
