Keyamo said Dogara never left the APC when he was in the Peoples Democratic Party, PDP.
Dogara had on Friday defected from the PDP to APC.
His defection was disclosed by the acting Chairman of APC, Mai Mala Buni after they met with President Muhammadu Buhari at the Presidential Villa.
Reacting, Keyamo in a tweet wrote: “Welcome back home, Rt. Hon. Yakubu Dogara, my classmate, my brother and friend. You really never left us in spirit!”
