When you enter the utility tunnel, there is a copy of Pugilism Illustrated, a workbench, and an ophthalmoscope in a side room to the right. To get to the White House, take the first left, follow the corridor, and you will eventually find a door to the left that opens onto the ruin-filled radioactive pit that the White House has become. To reach the Presidential sub level in Broken Steel, keep following that corridor until you see a door on the right.
At the intersection where the unlucky daredevil hung himself from the light, taking the path west and following it around will yield a cash register with pre-War money. A few steps north of the register is a first aid box in the rubble.
There are two ramps set up on either side of a car and the remains of a daredevil trying to keep himself entertained after the bombs fell. You can see on one side the crashed motorcycle and the top half of the daredevil hanging from the light fixture above the car. However, it is possible for the skeleton to have fallen down and be lying on the car instead.
