Senator Amos Wako and MPs Paul Otuoma (Funyula) and Godfrey Odanga (Matayos) publicly clashed with Governor Sospeter Ojaamong over claims of graft in the county.
Mr Ojaamong is among eight governors the Senate has recommended for investigation over misappropriation of funds.
Speaking at a funeral in Matayos, they demanded answers from the county government over missing money and challenged the governor to explain how the unaccounted-for funds were spent.
