Adidas to launch investigation into allegations of inappropriate behavior made against Kanye West
Adidas is starting an investigation into allegations of misconduct made against Kanye West, with whom the company had a partnership that it ended in October.
A statement by Adidas on Thursday said: "It is currently not clear whether the accusations made in an anonymous letter are true. However, we take these allegations very seriously and have taken the decision to launch an independent investigation of the matter immediately to address the allegations."
The statement follows an article in Rolling Stone which reported that Adidas' board members ignored inappropriate behavior from the rapper, who legally changed his name to Ye in partnership with his Yeezy brand.
Rolling Stone said it obtained a letter about "the toxic and chaotic environment that Kanye West created" sent by Yeezy's former high-ranking employees to Adidas' executive board members on Tuesday.
The letter went further to state that "This type of response from a brand partner is one that Adidas employees should never be subjected to, nor should Adidas leadership ever tolerate."
Adidas ended its partnership with Ye after the rapper made a series of antisemitic remarks in recent months.
In late October, West addressed the antisemitic comments — as well as what he said about George Floyd and Black Lives Matter — in a rambling 16-minute video shared by WmgLab Records on YouTube and which seemed to have been recorded at some point after Adidas ended its business relationship with him.
He told a small crowd that he thinks "Adidas felt like cause everyone was ganging up on me that they had the right to just take my designs."
In the video, West, who did not apologise for his antisemitic remarks, seemed to try to distance himself from any "hate group".
"I have no association to any hate group," he said as he closed his remarks in prayer, adding that "If any hate happens upon any Jewish person, it is not associated (gestures to himself) because I am demanding that everyone walk in love."
Adidas had been in partnership with West since 2013, when the company signed the rapper's brand away from rival Nike.
In 2016, Adidas expanded its relationship with West, calling it "the most significant partnership ever created between a non-athlete and an athletic brand".
Currently, West does not have an attorney or publicist representing him in the allegations against him.
