Washington - The US House of Representatives is expected to vote along party lines later Wednesday on an unprecedented 825- billion-dollar economic stimulus package to help pull the world's largest economy out of its most serious recession in decades.
President Barack Obama, who has made the stimulus a centrepiece of his efforts to revive the struggling economy, made a final effort to convince skeptical legislators to back his plan, which includes a mixture of government spending projects and tax cuts for consumers and businesses.
