In this country tonight, PBS shows one of the most talked about tributes of the year.

The president who did the most for black Americans in 20th century history was Lyndon Johnson, and he got his hands dirty by dealing with Southern senators, Southern congressmen, horse trading with them, cajoling them, learning what not to talk about. And he got civil rights passed and Great Society programs. That should be the model. Get over yourself.

The Republican presidential candidate [Donald Trump] provoked condemnation from leaders in both parties and around the world. He did that by proposing to bar all Muslims from entering the United States.

When I go to American cities and speak to American audiences about Karachi, I am able to draw their own wonder and consternation about the cities they live in as an entry point to this other faraway, instant city.

Republicans are now trying to stop Donald Trump. And there was much more ferocious and widespread criticism from Republicans of Trump this time around.

So many awful things have happened in Karachi, it's true. It has its own crazy rhythm. Even as crazy as other news is in Pakistan, the city manages to beat that in the frequency of catastrophes.

People who want a different Pakistan have to find a way to go back into their own past and revive the vision of their founders, that was clearly a tolerant and diverse one, so that they can distinguish it from the one that has been imposed upon it. If they can do that, they can take back this city and their country.
