Some folks believe a person cannot be injured enough to receive a check, yet still healthy enough for the most stressful and demanding job on the planet.
The disclosure of the Navy benefit for injuries incurred as a Vietnam POW may raise fitness questions.
Sen. John McCain has long said he is in robust health and is strong enough to hike the Grand Canyon, but he also is receiving what his staff Monday termed a "disability pension" from the Navy.
When McCain released his tax return for 2007 on Friday, he separately disclosed that he received a pension of $58,358 that was not listed as income on his return.
On Monday, McCain's staff identified the retirement benefit as a "disability pension" and said that McCain "was retired as disabled because of his limited body movements due to injuries as a POW."
McCain campaign strategist Mark Salter said Monday night that McCain was technically disabled. "Tortured for his country -- that is how he acquired his disability," Salter said.
Certain types of military and veterans pensions are either partially or completely tax-exempt, depending on the seriousness of the disability. In McCain's case, the exemption is 100%.
