FBI Director James Comey said the new emails did not change the bureau's earlier decision. The FBI again decided that no charges should be brought against Clinton for her use of a personal email server while she was U.S. secretary of state.
Comey sent a letter to members of Congress with his findings two days before the U.S. presidential election.
The FBI launched an investigation in 2015 into Clinton's use of a private email server. Investigators tried to find out if Clinton had sent secret government information through the private server.
The emails were written before she became the Democratic Party's candidate for president.
In July, Comey announced the FBI investigation had not found enough evidence to charge Clinton with a crime. But he did say the investigation found she had been "extremely careless" in her email practices.
On October 28, Comey sent a letter to Congress stating that the FBI had found a new group of emails that could be important to the investigation. The emails were discovered in a separate investigation involving former Congressman Anthony Weiner, the husband of top Clinton advisor Huma Abedin.
10月28日，科米致信国会声明联邦调查局发现了一堆可能对这起调查非常重要的新邮件。这些邮件是在另一起针对前国会议员安东尼·韦纳（Anthony Weiner）的单独调查中发现的，韦纳是希拉里高级顾问胡马·阿比丁（Huma Abedin）的丈夫。
Comey was criticized by many Democrats and some Republicans for the FBI's decision to make the email investigation public. The decision came as opinion studies showed the presidential race becoming close in the days before the election.
The critics argued that the decision could possibly change the minds of voters and influence the outcome of the election. Some also suggested Comey's action may have violated the U.S. Hatch Act, which sets limits on the political activities of federal employees.
In his latest letter, Comey wrote that FBI investigators had reviewed a large number of newly discovered emails since October 28. "Based on our review, we have not changed our conclusions that we expressed in July with respect to Hillary Clinton while she was secretary of state," he wrote.
Historically, federal government agencies have attempted not to get involved in politics during election campaigns.
The Clinton campaign welcomed Comey's latest decision regarding the investigation. "We were always confident nothing would cause the July decision to be revisited. Now Director Comey has confirmed it," campaign spokesman Brian Fallon said on Twitter.
希拉里竞选团队对科米关于调查的最新决定表示欢迎。希拉里竞选发言人布赖恩·法伦（ Brian Fallon）在推特上表示，“我们一直相信没有任何因素会导致7月份的决定被重新审查。现在科米局长确认了这点。”
Trump reacted by saying Clinton is "being protected by a rigged system." He also questioned how the FBI could have examined all the emails, which reportedly numbered in the hundreds of thousands. "You can't review 650,000 new emails in eight days. You can't do it, folks," Trump told supporters during a rally Sunday.
