The White House announced on Thursday that President Donald Trump has been diagnosed with chronic venous insufficiency (CVI). The announcement followed growing public speculation over visible swelling in the president's legs and bruises on his hands.

Leavitt said Trump noted "mild swelling in his lower legs," which prompted the White House medical team to evaluate him. They concluded that Trump has chronic venous insufficiency -- a condition in which there isn't adequate blood flow in the veins in the legs. This can cause the blood to pool, causing swelling in the lower legs.
