Hillary Clinton's campaign has urged the Federal Bureau of Investigation to disclose any information it has on Republican presidential candidate Donald Trump's links with Russia, Reuters reported on Wednesday. The United States Democrat candidate's campaign accused the agency of bias after it announced that it would launch a fresh investigation into Hillary Clinton’s private email server case.

FBI Director James Comey has been accused of breaking the law by announcing the new investigation just days before the presidential election. The case pertains to Clinton's use of personal email addresses connected to a privately-owned server, rather than a government email, during her tenure as President Barack Obama's first-term secretary of state.

The FBI had initiated a primary investigation into Trump's links with Russia, but found no evidence to make a public disclosure, Reuters reported. Following the FBI's decision on Clinton, the latest poll conducted by ABC News and The Washington Post shows Trump leading his opponent Hillary Clinton 46%-45% among voters in the run up to the November 8 election. Describing the numbers as "bad polling", Clinton's campaign dismissed the poll's result as a consequence of FBI's disclosures, The Guardian reported.

According to The New York Times, earlier this year, the FBI and Justice Department had decided against disclosing details involving Trump's campaign chairperson Paul Manafort and secretive business dealings in Ukraine earlier this year, thus demonstrating that Comey's announcement on Clinton last week broke the agency's pattern on such cases. Officials also told The New York Times that government entities also chose to not divulge details about Clinton's relationships with donors to her family foundation. The Justice Department had reportedly urged the FBI to not issue any subpoenas in the case either.

The FBI's announcement on the Clinton case came after new emails were found on a computer seized during an investigation of sexually explicit text messages sent by former congressman Anthony Weiner. to an underage girl.

Both presidential nominees have directly attacked each other and their policies, with Trump also accusing the US media of covering his campaign unfairly to help Democratic candidate Hillary Clinton. The businessman said if he was elected, he would sue around a dozen women who have accused him of sexual harassment. The assault allegations have rapidly come to the fore after a video surfaced showing him boasting about forcing himself on women.
