“I knew Tim was sympathetic about my recent injuries but I didn’t think he had to go this far to show me how strongly he felt,” Barbara Johnson said in a statement released Monday.

Johnson fell the same week the Senate passed a resolution on fall prevention awareness. The Hill reported that the resolution designated Sept. 22, 2012, as "National Falls Prevention Awareness Day."

In 2006, Johnson suffered a severe brain bleed and had brain surgery. He returned to his work in the Senate just a few months later after extensive work with physical, speech and occupational therapists. His mobility and speech have been left slightly affected.
