(VOVworld) - President Barack Obama urged the US Congress Thursday to avoid contributing to global economic uncertainty by passing a budget before the end-of-September deadline and preventing a government shutdown. Obama said "It's been a volatile few weeks around the world. There's been a lot of reports in the news, and stock markets swinging, and worries about China and about Europe". Obama called on Congress to pass a budget, prevent a shutdown, and not to worry businesses and workers by contributing unnecessarily to global uncertainty. He stressed that Congress should avoid attaching to the bill "unrelated partisan issues".
