Kanye West has accused Wisconsin Democrats of spying on his presidential campaign after they claimed he submitted his nominations papers late and filed bogus signatures. On Friday, the state's Democratic Party filed a challenge to block the rapper from running as a third party candidate citing numerous problems with his paperwork including incorrect addresses for circulators and fake signatures. In response to the complaint, West claimed the party hired a private investigator to spy on his team as part of an 'organized effort of harassment and intimidation' against his presidential campaign, according to documents obtained by TMZ.
