Sarah Palin's record in office is facing increasing scrutiny after it emerged that she misled Republican supporters when she was presented to the nation as Senator John McCain's running mate.
Mrs Palin told a cheering audience in Ohio that she had turned down an offer from the US Congress to build the so-called "Bridge to Nowhere", which would have connected Gravina Island with Ketchikan International, an airport in Alaska's southeast serving just 200,000 passengers a year. Mr McCain routinely cites the £100 million project as a symbol of wasteful central government spending.
As she introduced herself to Republicans and the American public on Friday, the virtually unknown Mrs Palin said: "I championed reform to end the abuses of earmark spending by Congress. In fact, I told Congress ... 'thanks, but no thanks' on that bridge to nowhere. If our state wanted a bridge, I said we'd build it ourselves."
However it emerged that in a 2006 interview with the Anchorage Daily News during her gubernatorial campaign, Mrs Palin had a different view of the bridge.
