JUDY WOODRUFF:

While the Republican Party has seen its share of conflicts this week, recent events have also unearthed discord within the ranks of the Democrats as well.

The hacking of Democratic National Committee e-mails, experts say by the Russian government, and the posting of e-mails on WikiLeaks, led to the resignation of DNC Chairwoman Debbie Wasserman Schultz and other top officials, and exposed rifts within the party.

But the revelation also caused speculation about how WikiLeaks got them and why they released them.

So, we decided to talk to Julian Assange, the founder of WikiLeaks, from the Ecuadorian Embassy in London, where he has been holed up for four years to avoid extradition to the U.S.

I spoke with him a short while ago.

Julian Assange, welcome.

You said this week that WikiLeaks is going to be releasing more of the information that was hacked from the Democratic National Committee in different batches. So when will the next batch come?
