Wikileaks has released nearly 20,000 emails it says are from the accounts of Democratic National Committee officials.

The release could cloud the upcoming Democratic party convention, which kicks off next week in Philadelphia.

It is unclear how Wikileaks obtained the records, but the release comes weeks after a hacker (or hackers) going by the name Guccifer 2.0 began releasing records obtained through the DNC's computer systems. The hacker claims to be Romanian, but many suspect that the records were taken by a team of Russian hackers.

Guccifer 2.0 has said that they obtained DNC emails. Other documents released by the hacker(s) include internal planning memos and databases of Democratic donors.
