WikiLeaks posted 14 minutes of audio of what it claimed were hacked voicemail messages from top Democratic officials Wednesday, just before Vice President Joe Biden and President Barack Obama were to address the Democratic National Convention.
NBC News hasn't authenticated the 29 files and isn't quoting from them. In general, they appear to mirror some of the more than 19,000 hacked Democratic National Committee email messages that have been published in the last week. Information in some of those messages led to the ouster of DNC Chairwoman Debbie Wasserman Schultz.
The alleged voicemails add little new of particular note. But their publication appeared to have been timed to cause maximum embarrassment for Democratic presidential nominee Hillary Clinton.
WikiLeaks' founder, Julian Assange, is under investigation by the U.S. Justice Department for his role in the organization's leak of sensitive diplomatic cables during Clinton's four years as secretary of state.
In an interview on British television last month, Assange said it was his "personal perspective" that a Clinton presidency would be "a bit of a problem for freedom of the press" in general. He said last week that more leaks are in the works to damage Clinton.
The FBI said it had no comment on the alleged voicemails, telling NBC News on Wednesday that it continues to investigate the hacking.
