Donald Trump just can't stop attacking black icons, but he's a loser every time.

Donald Trump’s racism is never so evident as when he’s trying to prove how racist he isn’t.

Rap legend and music mogul Jay-Z spoke out this weekend about Trump’s racist “shithole countries” rant, telling CNN’s Van Jones that “Everyone feels anger, but after the anger it’s really hurtful because he’s looking down on a whole population of people and he’s so misinformed because these places have beautiful people.”

Jay-Z also compared racism with toxin-resistant pests, and called Trump “the super-bug.”

On Sunday morning, Trump responded to Jay-Z’s comments by attacking him on Twitter, and taking credit for President Barack Obama’s policy achievements.

“Somebody please inform Jay-Z that because of my policies, Black Unemployment has just been reported to be at the LOWEST RATE EVER RECORDED!” Trump tweeted.

Trump’s statement is, of course, a lie. The downward trend in black unemployment occurred mostly during Barack Obama’s presidency, and continued under Trump as a result of Obama’s policies.

But more telling than Trump’s lie is his racism. He has made a consistent habit of attacking black role models who speak out against him, and ignoring similarly situated whites. For example, Trump never attacked white rap superstar Eminem after his blistering assessment of Trump at the BET Hip-Hop Awards.

Conversely, Trump is quick to attack black people whom he feels have not shown him proper respect.

In the span of a week, Trump attacked black NFL players for protesting racism, demanded the firing of journalist Jemele Hill, and uninvited NBC star Steph Curry to the White House after Curry said he might not go.

While Trump consistently attacks CNN as a network, he has singled out people of color at CNN for abuse, including Don Lemon. Trump and his team have waged a campaign of attacks against Black Journalist of the Year April Ryan, even declaring her an “enemy.”

And Trump kicked off his presidency by attacking civil rights hero John Lewis, and smearing his black constituents in the process, just before his inauguration.

But Trump’s attacks have generally backfired, and this one will be no exception.
