Jewish philanthropist and the Republican party’s biggest donor, Sheldon Adelson, was diagnosed with non-Hodgkin lymphoma and has been out of office since December, The Marker reported.
Adelson, 85, suffers from side effects of the medication he is taking to treat the disease, Los Vegas Sands spokesman Ron Reese said.
Adelson also suffers from peripheral neuropathy, which makes it difficult to walk.
The billionaire’s illness was noticed after his attorney said that he could not bear witness in court due to health issues.
Adelson was expected to testify in the case brought by Hong Kong businessman Richard Suen and his company, Round Square Co. He testified in 2013 and 2008 in the case’s two previous trials.
Suen has been seeking compensation because he said he helped Sands secure business in the Chinese gambling enclave of Macau. Sands has argued Suen didn’t help get crucial approval to build casinos in Macau and deserves nothing.
Sheldon and his wife Miriam gave President Trump’s campaign $30 million in 2016. They followed that by contributing $100 million to the Republican Party for the 2018 midterm elections.
