President Obama has said he is "exasperated" by the failure to agree a deal with Republicans over the US budget which has forced the government into shutdown.
The US government closed non-essential operations on Tuesday after Congress failed to reach a new budget deal.
Talking to US network CNBC he said the situation was "entirely unnecessary".
