Many social media users, mostly men, claimed that the Citizen journalist was misleading men with his advice on polygamy but failed to lead by example.
A defender of monogamy responded to men attempting to criticize him as the chairman of the Men's Conference.
Letoo criticised those men, rebuking them for not attending his wedding and threatening to suspend them.
"All those making noise on social media will be suspended immediately. You cannot attack the chairman and fail to attend an event held at Ole Ntimama Stadium," he said.
Letoo revealed that he was surprised by the turnout at his wedding, saying he expected only 10,000 people to attend.
"The turnout surprised me; I only reserved space for 10,000 people in the tents and was amazed to find the stadium full. I was both happy and embarrassed at the same time. If I had known there would be so many people sitting on the mounds, I would have hired cleaners to wash them because they were dusty," he said.
