Washington: The Republican candidate for the White House, Donald Trump, on Sunday denounced that it is impossible to review 650,000 emails in eight days, as a response to the announcement that the FBI has not changed its decision of not prosecuting his Democratic rival, Hillary Clinton, after having reviewed the new evidence.

During a rally in Michigan, Trump said that the investigation on his rival's emails will go on for a long time and urged the people to vote on Tuesday to put an end to, according to him, "the same rigged system that's protecting Hillary Clinton is the system that's stolen your jobs and shipped our wealth overseas and to Mexico."

Trump was responding to a letter from the Director of the Federal Bureau of Investigation (FBI), James Comey, sent to Congress on Sunday to report that its decision not to prosecute Clinton has not changed after having reviewed the new emails on the computer of one of the former Secretary of State's assistants.

The FBI found around 650,000 emails on the laptop of the former Congressman Anthony Weiner, a former partner of Huma Abedin, one of Clinton's closest advisers.

Less than two weeks before the presidential elections on Tuesday, Comey launched an investigation into these emails, which are apparently linked to the use of a private email server by Clinton which allegedly included classified information while she was serving as Secretary of State (2009-2013).

"Hillary Clinton is guilty. She knows it, the FBI knows it," Trump said on Sunday at the rally in Michigan, one of the most hard-fought states in the final stretch of the race for the White House.

Without mentioning Comey, Trump said that it is time "to deliver justice at the ballot box" and that "the rank-and-file special agents in the FBI will not let her get away with her dreadful crimes."

The FBI had concluded in July that the former Secretary of State's usage of a private server to transmit government communications, including some emails with classified information, did not justify an accusation against the now candidate to the White House.

In the letter released on Sunday, Comey told several congressmen that the FBI has been working around the clock to process and review every email from Weiner's computer.
