A key Trump ally has come under fire for saying he hopes that Barack Obama dies next year.

Carl Paladino, who served as New York co-chairman for President-elect Donald Trump’s campaign, let loose an intemperate tirade when interviewed by Artvoice, a New York arts publication.

Asked what he most wished for 2017 he replied: “Obama catches mad cow disease after being caught having relations with a Herford.(sic) He dies before trial and is buried in a cow pasture next to (senior White House adviser) Valerie Jarrett, who died weeks prior, after being convicted of sedition and treason, when a Jihady cell mate mistook her being a nice person and decapitated her."
