They are Julius Ochen, the Kapelebyong County Member of parliament; Herbert Ariko, Soroti Municipality and Soroti Woman MP, Angelina Osege.
Okabe belongs to the ruling National Resistance Movement party.
The MP accused Okabe of telling Museveni during his recent visit to Bukedea district that all members of Teso Parliamentary Group support the scrapping of the presidential age limit, a claim he dismissed as false.
Ariko, who has been the secretary general of the group, said he is tired of being part of a weak leadership, saying he will only return once a new leadership is put in place.
The group is comprised of 33 members of parliament drawn from all the constituencies in Teso sub region.
