US election: Clinton says she will focus on issues, not Trump
US 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."
She was speaking to reporters aboard her campaign plane.
Mr Trump used a rally in Gettysburg to promise curbs on lobbying and new trade and climate change negotiations.
With just 16 days until the election, much of the recent focus has been on controversies linked to his campaign.
