WASHINGTON, D.C.: The FBI announced on Monday (Tuesday in Manila) it was investigating the embarrassing hack of Democratic National Committee emails — a breach the Clinton campaign blamed on Russia, accusing Moscow of seeking to influence the US presidential election. The emails leaked by WikiLeaks, which reveal that party leaders sought to undermine the campaign of Hillary Clinton’s rival Bernie Sanders, threw the Democratic National Convention into disarray on its first day and prompted the party boss to resign. While a series of experts pointed the finger at Moscow, others urged caution. Russia denied any involvement. “The FBI is investigating a cyber intrusion involving the DNC (Democratic National Committee) and are working to determine the nature and scope of the matter,” the agency said, making no mention of possible culprits.
