Today, Donald Trump proved, once again, that he has an 'inability to think for an extended time about anybody but himself'

In a March 16, 2016 column, New York Times op-ed columnist David Brooks wrote, "....major Republicans are raising their heads and highlighting [Donald] Trump’s actual vulnerability: his inability to think for an extended time about anybody but himself."

We saw that today when Trump turned a White House event marking Black History Month into an attack on the media.

In a post on the Toronto Star's website headlined "Donald Trump just gave a Black History Month speech about the persecution of Donald Trump," Washington correspondent Daniel Dale wrote:

WASHINGTON—Happy Black History Month, everyone. Have you heard about the greatness and persecution of Donald J. Trump?

The president of the United States held an “African-American History Month listening session” in the Roosevelt Room of the White House on Wednesday. He began with a five-minute monologue that was more about himself — his campaign, his alleged mistreatment by the media, his popularity — than it was about African-Americans.

Trump’s third paragraph, for example, started with a single sentence about the Rev. Martin Luther King Jr. It was followed by 10 sentences of grievance about his alleged mistreatment by the media.

Note that in the video above, Trump calls the media "very dishonest people."

At another point during the event Trump calls CNN "fake news."

This from a man who for years perpetuated the lie that America's first African-American president was not born in the United States.
