Thousands of supporters of the US conservative Tea Party movement have gathered for a rally led by Republican politician Sarah Palin.
She urged the crowd to sack Senate majority leader Harry Reid in mid-term elections, along with other Democrats who backed healthcare reform in November's mid-term elections.
About 7,000 people assembled outside Mr Reid's home town, the tiny former mining settlement of Searchlight, in the state of Nevada, the BBC reports
A nationwide bus tour intended to drum up support for the Republicans is due to follow.
The US House of Representatives narrowly passed the landmark healthcare reform bill earlier this week, with no Republican backing. It extends health care coverage to 32 million more Americans.
The Tea Party movement emerged from the various groups and individuals opposed to health care reform.
Mrs Palin, a former vice-presidential candidate and ex-governor of Alaska, came to Nevada a day after leading a rally in Arizona in support of her 2008 presidential running mate, John McCain, who is facing a stiff challenge from a conservative Republican in his bid for a fifth term in the Senate.
