Democratic hopeful Barack Obama has paid tribute to Hillary Clinton for her "valiant campaign" to become the party nominee for US president.
He said his former rival had "shattered barriers on behalf of my daughters and women everywhere".
The praise came after Mrs Clinton formally abandoned her bid for the nomination at a rally in Washington.
She said Mr Obama had proved his "grace and grit", and she urged her supporters to put their energy into electing him.
Mr Obama is expected to face the Republican presumptive nominee, John McCain, in November's presidential election.
In a statement, Mr Obama said he was "thrilled" to have Mrs Clinton's endorsement.
