Worry for Hillary Clinton's campaign as she faces FBI questioning


An FBI grilling into Hillary Clinton's reported use of a private email server could spell trouble for her bid to become the next US president.

The presumptive Democratic presidential candidate was quizzed by agents over her use of the server as secretary of state, but her campaign insisted that the interview - part of a year long probe - was expected and is unlikely to lead to a prosecution.

Questioning lasted for three and a half hours on Saturday morning at FBI Headquarters in Washington.

Secret Service stand guard at Clinton's home.

Clinton's spokesman, Nick Merrill, said: "She is pleased to have had the opportunity to assist the Department of Justice in bringing this review to a conclusion," but said the would not be commenting further "out of respect for the investigative process."

But while some legal experts have reportedly said that interview could suggest that the ongoing probe is reaching an end, barely a month away from formal nomination as party candidate the situation represents a serious major risk for Democrats.

Meanwhile, Republican presumptive nominee, Donald Trump, has jumped on the issue as an opportunity to undermine Clinton's fitness for office, referring to her as "Crooked Hillary".

However, USA polls still suggest she is well-placed to become America's first female president, even though many voters remain unsure about her trustworthiness.
