Once you attempt the question then PrepInsta explanation will be displayed.
The collective noun ‘committee’ is used to refer to a single unit here. So, it is singular, and the verb associated with it is ‘has’.
When verbs associated with suggestion (such as advise, ask, demand, insist, prefer, propose, recommend, request, suggest and urge) are used with a noun clause beginning with ‘that’, the clause uses the base verb. This is regardless of whether the noun in the clause is singular or plural. So, in the given sentence, ‘recuse’ is correct.
Also note that both ‘whether he is re-elected or not’ and ‘whether or not he is re-elected’ are grammatically correct.
