WASHINGTON: Federal investigators have secured a warrant to examine newly discovered emails related to Hillary Clinton`s private server, a source familiar with the matter said on Sunday, as a prominent Democrat accused FBI Director James Comey of breaking the law by trying to influence the election.

The warrant will allow the Federal Bureau of Investigation to examine the emails to see if they are relevant to its probe of the pri-vate email server used for government work by Clinton, the Democratic presidential nominee, while she was secretary of state from 2009 to 2013.

James Comey came under heavy pressure from Democrats on Sunday to quickly provide details of the emails, as Clinton allies worried the prolonged controversy could extend beyond the Nov 8 election and cast a shadow over a Clinton transition if she wins the White House.-Reuters
