WASHINGTON (Reuters) - The DNC has been hacked again.
And the finger - again - is being pointed at Russia.
The head of the US Democratic National Committee says Russian state-sponsored agents are behind the latest cyber attack.
The leaked documents were posted on WikiLeaks' Twitter account and attributed to alleged hacker Guccifer 2.0.
The infamous hacker leaked internal DNC documents in July that roiled the party ahead of its summer convention.
The most recent hack includes information on the party's finances and personal contacts of donors.
It also reportedly contains the cell phone number of presidential candidate Hillary Clinton's running mate Tim Kaine.
Russia has been accused of trying to influence the US presidential election through cyber attacks.
Republican presidential nominee Donald Trump in July invited Russia to dig up emails from Mrs Clinton's time as secretary of state prompting Democrats to accuse him of urging foreigners to spy on Americans.
And newly revealed emails reportedly hacked from the personal account of Mr Colin Powell show the former secretary of state calling Trump a quote "national disgrace" and "international pariah".
He also reportedly expressed dismay that the Clinton camp was trying to drag him into her email scandal.
