US first lady Michelle Obama has praised Barack Obama in a prime-time Democratic convention speech as a devoted husband and caring father at home and a "man we can trust" to revive the country's weak economy as president.
Mrs Obama, given a huge ovation and describing herself as the "mom in chief," made no mention of Republican challenger Mitt Romney in her Tuesday night speech closing the convention's opening day.
She urged voters to return her husband to the White House despite the agonisingly slow recovery from recession.
She says her husband reminds her "that change is hard, and change is slow and it never happens all at once" but "eventually, we get there, we always do."
