First of all, Wikileaks is the unofficial service of the Russian government. They have never published anything substantial about Putin or Russia, focusing on the pro-Kremlin agenda.
In the past third parties have offered them source material for publication, but they rejected it outright if it was anti-Kremlin - the most famous example were SurkovLeaks, gigabytes of mails related to Putin’s number two advisor ofered by the hacker group CyberJunta.
Not only did they refuse to publish the SurkovLeaks, but screamed “fake, fake” long after Kremlin tacitly admitted it was true (passport scans and family photos of Surkov played a part in the verification as well as confirmation from his e-mail correspondents).
Also, for a supposedly independent organization they went out of the way to attack the Golden Shower dossier. A logical reaction would have been “We don’t know about it, this didn’t go through us and we can’t determine it’s authenticity” but they screamed “everything in it is fake!”. A bit strange, don’t you think?
In the French Presidential race, which is a three-horse race, Wikileaks have prepared extensive leaks for Macron and Fillon, centre-right and independent candidates respectively not financed by Russia. The far right Marie Le Pen is financed by Russian banks and is a staunch advocate of Russian foreign policy. These claims are not for debate as she cheerfully acknowledges them, the last instance being her CNN interview.
So even a cursory glance at their Twitter feed shows they’re pro-Trump, anti-NATO and pro-Russian:
