I don't care whether you're driving a hybrid or an SUV. If you're headed for a cliff, you have to change direction. That's what the American people called for in November, and that's what we intend to deliver.

It is legitimate for the Turks to try to defend themselves.

Today, we are closer to fulfilling America's promise of economic and social justice because we stand on the shoulders of giants like Dr. King, yet our future progress will depend on how we prepare our next generation of leaders.

Education can unlock a child's potential and remains our strongest weapon against injustice and inequality.
