Will no longer respond to Trump, says Clinton

Washington: US Democratic presidential candidate Hillary Clinton has said she will no longer respond to her Republican rival Donald Trump and instead dedicate the final stretch of her campaign in discussing her proposals for the upcoming November 8 elections.

"I do not even think about answering (Trump) any more," Clinton told the media on Saturday while travelling from Pittsburgh to Philadelphia as she made campaign stops in both cities located in Pennsylvania.

The Democrat, who leads Trump in the polls, said she had already debated with her opponent for four and a half hours in the three presidential debates.

"I'm going to let the American people decide between what he offers and what we offer. So he can say whatever he wants to," Efe news quoted Clinton as saying.

Trump's electoral offensive has been marked by attacks on Clinton, accusing her of being the media favourite and alleging the elections are "rigged".

On several occasions, the business mogul has reiterated that if elected, he intends to launch an investigation into Clinton over her use of a private server to send official emails while she was Secretary of State, warning that it could even spell a jail sentence for her.

In the final debate between the White House hopefuls in Las Vegas last week, he called Clinton "a nasty woman".

The former first lady has stressed that Trump "can run his campaign however he wants to, he can go off on tangents", while she is determined to talk about "what we (Democrats) want to do".

In the two campaign events held on Saturday in Pennsylvania -- a key state for election victory -- Clinton was accompanied by her running mate Tim Kaine.

On Sunday, President Barack Obama will take part in a pro-Clinton rally in Nevada, another battleground state that could sway the final results of the hotly-contested election.
