U.S. Democratic candidate Hillary Clinton has said she no longer cares what her Republican rival Donald Trump might say and will focus on issues instead.
“I debated him for four and a half hours,” she said, recalling their acrimonious exchanges. “I don’t even think about responding to him anymore.”

For Republicans, it could mean the start of a long-term political nightmare.
Speaking on stage in Pittsburgh, Mrs Clinton called for Americans to unite.
