Adelson, 85, has been out of his office since late December due to side-effects from his treatment for non-Hodgkin’s lymphoma. A lawyer representing one of Adelson’s casinos referred to his health as “dire” in court Monday.
A company spokesman told Bloomberg that Adelson’s illness has not kept him from acting as the chairman and CEO of the Las Vegas Sands Corp., Adelson’s casino empire. However, Adelson missed a call to investors in January.
Adelson is worth $39 billion, according to the Bloomberg Billionaire Index. He was the largest outside spender during the 2016 elections, and has donated hundreds of millions of dollars to Jewish and Israeli causes.
