Washington - President Barack Obama will offer assurances that the United States can recover and emerge stronger from its worst economic crisis in decades, according to released excerpts of his speech to be delivered Tuesday evening to Congress.

"While our economy may be weakened and our confidence shaken, though we are living through difficult and uncertain times, tonight I want every American to know this: we will rebuild, we will recover, and the United States of America will emerge stronger than before," Obama will say, according to the excerpts released by the White House.

Obama is set to unveil details of his 2010 budget and other economic and foreign-policy priorities during the president's annual address before a joint session of Congress
- Obama's first since taking office in January.

"The weight of this crisis will not determine the destiny of this nation," Obama said amid a year-long, deepening recession confronting the world's largest economy.

"What is required now is for this country to pull together, confront boldly the challenges we face and take responsibility for our future once more," he said. (dpa)
