FULL ANSWER. Ford granted the blanket pardon to former president Nixon on Sept. 8, 1974, a month after Nixon had resigned from office in the wake of the Watergate scandal.
Hemosiderin staining is dark purple or rusty discoloration of the lower legs caused by chronic venous disease. A 2010 study found hemosiderin staining in all subjects with lipodermatosclerosis and venous ulcers. When vein valves fail, regurgitated blood forces red blood cells (RBCs) out of capillaries.
Leaking valves and hemosiderin deposits are associated with venous insufficiency more often than with PAD (peripheral arterial disease). PAD is a problem with arterial blockages. Unfortunately, there is not much that can be done to remove the hemosiderin deposits.
