Democrats clash over civil rights

Democratic rivals Hillary Clinton and Barack Obama have clashed over remarks by Mrs Clinton on civil rights that she says were distorted by the Obama camp.
Black leaders criticised her for saying Martin Luther King's dream of equality came true when President Lyndon Johnson signed the Civil Rights Act in 1964.
On Sunday she said Obama supporters had misrepresented this as a slur on King. Mr Obama denied accusing her of racism.
The black vote will be crucial in the South Carolina primary on 26 January.
It will be the first southern state to vote in the primary season.
Mr Obama and Mrs Clinton are leading the race to be the Democratic candidate in November's presidential election.
Both are aiming to build momentum before 22 states nominate their preferred candidate on 5 February, dubbed "Super Tuesday".
