Second cyber-hack

The FBI is investigating a cyber attack against another United States Democratic Party group, which may be related to an earlier hack against the Democratic National Committee, four people familiar with the matter have said. The previously unreported incident at the Democratic Congressional Campaign Committee and its potential ties to Russian hackers are likely to heighten accusations, so far unproven, that Moscow is trying to meddle in the US presidential election campaign to help Republican nominee Donald Trump. The newly disclosed breach may have been intended to gather information about donors, rather than to steal money, the sources said.
