ABC News -- It was a moving moment, the President's early Thursday morning trip to Dover to pay tribute to the fallen. President Obama has received both praise and criticism for doing it with television cameras. Liz Cheney called it a "surprising way for the President to choose to do this." But this morning Jarrett said that "it's important for us all to recognize what is at stakeI think it is a reminder about how deep the sacrifice is." Jarrett said the President wouldn't have done it if the families had objected. - George Stephanopoulos
