US President Barack Obama has put Vice President Joe Biden in charge of overseeing the implementation of his $US787 billion economic stimulus plan.
He has appointed Interior Department inspector general Earl Devaney to oversee how the money is spent. He will be chairman of the Recovery Act Transparency and Accountability Board.
His job will be to ensure that the stimulus funds are not wasted.
The president said that $US15 billion would be released on Wednesday to help states pay their healthcare bills.
The BBC reports some states have been struggling to pay for their Medicaid programmes, which provide healthcare for people on low incomes.
Mr Obama has warned state governors not to waste any of the stimulus funds.
