The official Palestinian Wafa news agency English website says:
Dr. Saeb Erekat, Secretary-General of Palestine Liberation Organization (PLO), told CNN that President of the State of Palestine Mahmoud Abbas wishes US President Donald Trump and First Lady Melania a speedy and full recovery.However, if you look at the "Presidency" section on the Wafa Arabic website where all Abbas' official statements and communications are, there is not a word about wishing Trump a recovery on that page.
Abbas' Facebook page likewise does not say a word about this.
Understand that every public word by Abbas is listed on those pages, like "The President congratulates the King of Lesotho on their Independence Day."
It's almost like Saeb Erakat is making things up to stall the freefall of Abbas' reputation in the US.
UPDATE: Just as I was publishing this, I saw this amazingly hypocritical tweet from Erakat:
Met with China’s 🇨🇳 Ambassador to Palestine 🇵🇸 QWA WEI . Appreciated China’s firm stand with int. Law , end the Israeli occupation. No to annexation and settlements . Two States 1967 borders. Help Palestine to fight COVID 19. pic.twitter.com/pYBED4Wf6Z

Yes, the Palestinian leaders are praising the Chinese government - which, as one commenter noted, is "the only regime in the entire world that has a systematic and openly admitted occupation and detention programme targeted at Muslims, Tibetans and Mongolians" - as a paradigm for upholding international law!
