Mrs Palin said it was time to "drill baby, drill, not stall, baby, stall"
Thousands of supporters of the US conservative Tea Party movement gathered in Boston for a rally led by Republican politician Sarah Palin.
Mrs Palin, who ran for the post of vice-president in the 2008 election, said it was time government started working for the people.
The rally, held on Boston Common, is part of a 20-day, 47-city tour dubbed Tea Party Express.
The last event in the series will be held in Washington DC on Thursday.
'Keep the change'
Mrs Palin told the 5,000-strong crowd that the Tea Party movement was taking America back and putting government back on the side of the people.
She criticised the administration of President Barack Obama for its health care reform, which she said could only be paid for by higher taxes, increasing US debt for generations to come.
She said that if that was the kind of change the Obama Administration was about, "we'll keep clinging to our Constitution and our guns and religion - and you can keep the change."
There were also plenty of references to the Boston Tea Party of 1773, when colonists dumped tea off English ships to protest what they considered unfair taxation by the British.
It is from this event that today's conservative movement takes its name.
Supporters say the final event in the series will see thousands of people protesting against tax increases, the budget and President Obama's stimulus programme.
Thursday's rally is scheduled to coincide with Tax Day, the annual US deadline for submitting tax returns.
