FBI Director James Comey has told Congress he has not changed a conclusion reached in July that Democratic presidential candidate Hillary Clinton did nothing criminal in using a private server for emails when she was secretary of state.
Comey made the announcement in a letter Sunday after the bureau reviewed a new batch of emails discovered during a separate investigation involving former U.S. Congressman Anthony Weiner, the estranged husband of key Clinton aide Huma Abedin.
In his letter to Congress, Comey said investigators have been "working around the clock" processing and reviewing the emails written to and by Clinton when she was secretary of state. Based on their review, he said, "we have not changed our conclusions that we expressed in July with respect to Secretary Clinton."
Comey said in July that while Clinton may have been "extremely careless" in handling classified information, there was no criminal intent and that prosecutors would reach the same decision.
Global financial markets rose following the announcement. Dow Jones index futures surged by about 200 points ahead of Monday's opening, according to the Associated Press.
In Asia, Japan's Nikkei jumped 1.6 percent, and Australia's S&P ASX/200 rose 1.3 percent. Other Asian markets saw gains 0.3 and 0.7 percent. However the Philippine benchmark index fell 0.7 percent.
Clinton communications director Jennifer Palmieri told reporters Sunday the campaign is "glad that this matter is resolved. We are glad to see that he (Comey) has found, as we were confident he would, that he's confirmed the conclusions that he reached in July."
Republican presidential nominee Donald Trump said Clinton is protected by a "rigged system," telling a crowd of supporters in Michigan that it is impossible to review "650,000 new emails in just eight days."
Voter opinion polls have tightened since Comey announced two weeks ago that more Clinton emails were uncovered.
Trump saw it as a gift, telling voters that the rival he loves to call "Crooked Hillary" would be impeached and face criminal investigations if she were elected.
With less than two days before millions of U.S. voters cast their ballots, the Clinton camp likely will use the Sunday letter from Comey as its gift.
Trump and Clinton have just one more full day to convince undecided voters that he or she should take over for President Barack Obama in January.
