Ruto continued the conversation by asking why he hadn't cut his hair.
"Why haven't you cut your hair?" the President asked.
The MP replied with much fanfare, "If you say so, I'll cut it."
His response made the President and others present burst into laughter.
The first-term MP is known for his slightly long hairstyle, which he rarely cuts.
