Trump says Clinton protected by 'rigged system' as FBI clears her over emails

Donald Trump has claimed Hillary Clinton is "being protected by a rigged system" after the FBI announced she would not face charges for her use of a private email server while she was secretary of state.

The Republican candidate dismissed the FBI's announcement as he addressed a crowd in Michigan, saying the agency had not done its job properly, but "rank and file agents" would not "let her get away with it".

"You can't review 650,000 new emails in eight days," he told his supporters, to loud cheers. "Hillary Clinton is guilty, she knows it, the FBI knows it, the people know it.

"She is being protected by a rigged system.

"Now it's up to the American people to deliver justice at the ballot box on November 8."

Mrs Clinton was exonerated by the FBI for a second time this year, as director James Comey revealed to Congress that investigators had finished reviewing emails, but found no evidence to change their conclusions made earlier.

In July, Comey had acknowledged that Clinton's use of a private email server was "extremely careless" but that her actions did not warrant charges.

He unwittingly threw the election into turmoil at the end of October when he announced that there were new emails discovered pertaining to the investigation, prompting fresh outrage at the Democratic candidate.

According to reports, Clinton rolled her eyes and shrugged at the news that Comey said there would be no charges.

Mrs Clinton's communications director Jennifer Palmieri said: "We're glad this matter is resolved".

Both candidates are embarking upon a frantic final day of campaigning before American votes on Tuesday to elect its next president.

As the campaign's final weekend drew to a close, more than 41 million Americans had already cast their ballots in early voting.

Mrs Clinton still appears to hold an edge over Mr Trump in the campaign's final stretch. The Republican has a narrow path to victory that requires him to win nearly all of the roughly dozen battleground states up for grabs.

Mrs Clinton plans to conclude her election campaign with stops in Pittsburgh, Grand Rapids, Philadelphia and Raleigh, North Carolina, on Monday.

Mr Trump is expected to visit North Carolina, Florida, Pennsylvania, New Hampshire and Michigan.
