In a statement on Wednesday, Raila complimented the former Justice minister for her elegance and command of the issues brought up in the discussion.
The Azimio family was pleased with her performance, he continued.
“Your composure, knowledge of the material, and ability to maintain demeanour under pressure were excellent. I congratulate Martha Karua, my competent deputy and team member. The Azimio family is pleased with the way you participated in the debate last night. Keep selling,” Raila said in a tweet.
In the second hour-long presidential discussion, Karua squared off against Rigathi Gachagua, the deputy presidential candidate for Kenya Kwanza.
