Republican Carly Fiorina, the outspoken former chief executive of Hewlett Packard who argued she would be the sharpest challenger against Democrat Hillary Clinton for the presidency, on Wednesday ended her White House bid.

"While I suspend my candidacy today, I will continue to travel this country and fight for those Americans who refuse to settle for the way things are and a status quo that no longer works for them," Fiorina said in a Facebook post, one day after she finished seventh in the New Hampshire primary.
