Remember, he said, a house divided against itself, cannot stand. The challenges we face today do not approach those of Lincoln's time, not even close. And we should be very clear about that.

In just the past week, we saw black men killed by police and five police officers killed by a sniper targeting white police. There is too much violence and hate in our country, too little trust and common ground.
