Kanye additionally wrote about issues on which he felt he could influence Trump, writing, "These issues include bullying, supporting teachers, modernizing curriculums, and violence in Chicago".
The rapper then continued tweeting, claiming that he and West worked together on the track, implying that he was the one who ultimately convinced West to sever ties with Trump. And before that, the 39-year-old rapper tweeted out the cover of Migos' latest album, Culture. The source added that the Muslim ban was the last straw.

The rapper stirred controversy before a high profile public meltdown when he voiced support for Mr Trump during a lengthy rant at a November concert.
After previously saying he would have voted for Donald Trump in the presidential election, Kanye West has now deleted all of his tweets supportive of the new president, according to TMZ.
