The Clinton Foundation was breached by hackers connected to the Russian government, according to a new report. The incident is separate from a breach of the Democratic National Committee announced last week.

The hack of the Clinton family’s nonprofit came as part of a broader campaign aimed at gathering data on more than 4,000 party officials, lawyers and foundations in the United States, according to unnamed officials who spoke with Bloomberg on Tuesday. The effort is thought to have lasted for about seven months, ending in mid-May.
