The FBI confirms it is investigating the Democratic National Committee’s hack. The FBI declined to elaborate but the outcome of its probe could have huge implications. The data breach was first disclosed last month, when hackers published confidential DNC files, including opposition research on Republican presidential candidate Donald Trump. A lone hacker known as Guccifer 2.0 has tried to take credit for the breach and denies having any ties to Russia. Russian officials have flatly denied any involvement with the DNC breach and said the hackers were not responsible.”]
