Bitan has been hooked up to the ECMO machine for two weeks, in serious yet stable condition following COVID-19 complications, after his initial hospitalization on December 13.
Likud MK David Bitan was hospitalized last week with COVID-19.
The ECMO machine pumps and oxygenates a patient's blood outside the body, allowing the heart and lungs to rest.
About 30 people were forced to enter quarantine after coming into contact with him.
"I thought I had the flu and nothing more," said MK Bitan.
Bitan tweeted on Thursday that he had participated alongside Prime Minister Benjamin Netanyahu in a ceremony welcoming about 500 new Olim from Ethiopia.
Bitan allegedly accepted hundreds of thousands of shekels when he was the vice mayor of Rishon Letzion in exchange for promoting the business interests of various powerful businessmen.
Blue and White leader Benny Gantz called Begin's announcement sad and said he hopes to earn his vote.
