US Commerce Secretary Penny Pritzker has warned that business is starting to suffer from the federal shutdown.

On Friday, the US defence contractor Lockheed Martin said it would put 3,000 workers on unpaid leave.
The US government closed non-essential operations on Tuesday after Congress failed to agree a new budget.
And President Barack Obama cancelled a scheduled trip to Asia because of the shutdown.
"The shutdown is not good for business. It's not good for the economy," Ms Pritzker said. One consequence of the shutdown had been her department's inability to collate vital economic data.
"We're a huge source of data for American business and that is a problem... It's affecting businesses and it's affecting their ability to get data," she said.
