According to the G1 news portal, the session could last up to 26 hours, but party leaders will try to close it at the end of the day. Witzel is expected to defend himself personally with an hour-long speech.
The continuation of the process will depend on the 47 votes approved or two thirds of the total of 70 deputies.
If the firing is approved by the plenary session of the chamber, the case goes to a mixed court made up of five deputies and five judges of the Rio Court of Justice (TJRJ).
Suspected of corruption amid the Covid-19 pandemic, the governor can answer for a crime of responsibility.
Then the court has up to 120 days to decide whether there was a liability offense.
If so, the authority would be removed from office. It was set aside by another decision of Minister Benedito Gonçalves, of the Superior Court of Justice.
The judge argued that the Federal Public Ministry discovered a sophisticated criminal organization, made up of at least three power groups, headed by Witzel.
The dismissal request was based on the alleged administrative impropriety and the misuse of public money in the health sector, based on the Placebo and Favorite operations.
Both actions of embezzlement investigated in the operation called Tris in Idem, which removed Witzel from his post on suspicion of corruption.
He is accused of receiving bribes from companies linked to the scheme through false contracts signed with the office of his wife and first lady of Rio, Helena Witzel.
The governor, who denies the charges, would have received at least 554,200 reais (about $110,000).
The Attorney General’s Office revealed the scheme after investigating irregularities in the contracts for field hospitals, respirators and medicines.
