Donald Trump says Hillary Clinton protected by 'rigged system' after FBI exoneration

STERLING HEIGHTS, MICHIGAN (WASHINGTON POST) - Republican presidential candidate Donald Trump cried foul after the FBI cleared his rival Hillary Clinton of criminal conduct in a new inquiry into the Democrat candidate's e-mails.

At a rally in the Detroit suburbs, Mr Trump insisted it would have been impossible for the FBI to review what has been reported to be as many as 650,000 e-mails in such a short time.

"Right now she's being protected by a rigged system. It's a totally rigged system. I've been saying it for a long time," he told supporters in Sterling Heights, Michigan.

"Hillary Clinton is guilty. She's knows it. The FBI knows it... Now it's up to the American people to deliver justice at the ballot box on Nov 8."

Trump has been praised in recent days for avoiding the kind of insults and outbursts that had alienated voters in the past. A New York Times article on Sunday said that campaign aides have wrested away control of Mr Trump's Twitter account, which the candidate had used to shoot himself in the metaphorical foot.

FBI Director James Comey said Sunday that the bureau had completed its examination of newly discovered e-mails connected to Mrs Clinton - an inquiry that had roiled the presidential race for nine days - and found nothing to alter its months-old decision not to seek charges against the former secretary of state for her use of a private e-mail server.

In a letter to congressional committee chairmen, Comey said investigators had worked "around the clock" to review the e-mails. The investigators found that the e-mails were either duplicates of correspondence they had reviewed earlier or were personal e-mails that did not pertain to State Department business, government officials said.

The e-mails were on a computer used by former congressman Anthony Weiner - the estranged husband of longtime Clinton aide Huma Abedin - that was seized during an FBI investigation into lewd text messages that Weiner is alleged to have sent to a 15-year-old girl.

In late October, Comey said that some of the e-mails on the computer, sent or received by Abedin, may have been "pertinent" to an FBI investigation of a private server that Clinton used to conduct government business.

On Sunday, however, Comey said that after reviewing e-mails on the computer, "we have not changed our conclusions expressed in July".

Most recent opinion polls show Clinton leading in all three, but Trump is hoping for a surge among white voters who lack college degrees.

At each stop on Sunday, Mr Trump was greeted by thousands of adoring fans. His aides saw these crowds as reason to hope for victories on Tuesday.

On Monday, the day before Election Day, Mr Trump's schedule reflects his tough position - needing to win a string of states where the race is either tied or he is behind.

He will hold five rallies in a day, jetting from Florida to North Carolina to Pennsylvania to New Hampshire and then to Michigan.

Mrs Clinton, by contrast, will appear in three states: North Carolina, Pennsylvania and Michigan.
