Renowned human rights lawyer Makau Mutua on Friday sent out a rare but sweet congratulatory message to celebrated KTN anchor Betty Kyallo.

Mutua was among fans who took to social media to congratulate the TV presenter on her last day at KTN where she worked for eight years.

"Great job . Keep doing what you do so well!" the US-based lawyer tweeted.

Betty, who is expected to take up a new role at K24, replied, "Thank you very much. I appreciate".

Mutua, however, was not done as he continued showering the celebrated journalist with praise - "You are the best — bar none!"
