The vocal Woman Rep has also accused her Governor of belittling her.
The vocal Woman Rep on Tuesday revealed that she has already reported the death threats to the police.
Wamuchomba hit the headlines last month when she called for rich Kikuyu men to consider marrying several wives.
The lawmaker, who once survived impeachment over her conduct, said that men who sire children with different women should consider taking them as their additional wives.
Wamuchomba at the same time accused Kiambu Governor Ferdinand Waititu of belittling her and others as the crisis in Kiambu over the county's leadership deepened.
County rivalry
This comes hours after Kiambu Deputy Governor James Nyoro accused Waitutu of dictatorship in the running of county affairs.
Nyoro disclosed that his boss had been taking issues including critical decision making in the running of the county in his hands, without involving key executive committee members.
“What has been happening in Kiambu is a one man show. There has not been any consultation between the governor and the county executive members and particularly the Deputy Governor,” Mr Nyoro said.
The sentiments by Mr Nyoro come on the heels of numerous complaints from a section of CECs who have spoken of frustration in executing their work.
However, Waititu maintained that he will openly speak out the truth on matters affecting the county saying he would not be cowed by his deputy.
He refuted claims that he has been running a county as a lone ranger faulting his deputy constantly being absent from office and taking frequent trips abroad.
