Senator Hillary Clinton has warned that the US economy may be on the brink of collapse, reports UPI.

"America's leaders don't have a vision, and the economy may be on the brink of collapse," the potential Democratic Party presidential candidate said.

"I don't see that thoughtful, visionary direction that got us where we are today...The progress that then occurred moved everyone forward. That progress is at risk today," she said.

Clinton also accused President George W. Bush of "looking the other way" while pressing issues -- such as the need for a national energy policy and healthcare reform -- went unaddressed.

But House Budget Committee spokesman Sean Spicer said Clinton's characterisation of the economy was inaccurate.

"Economic data, the outlook of top private forecasters and the Federal Reserve show that the US economy is in a sustained expansion with moderately strong growth, falling unemployment and increases in payroll jobs," a committee statement said.
