President Uhuru Kenyatta has been now asked to openly speak on alleged corruption in the National Cereals and Produce Board.
Further, the president has been asked to fire Agriculture Minister Mwangi Kiunjuri over the scam that reportedly saw at least Sh740 million lost.
Moiben MP Silas Tiren and his Nandi Hills counterpart raised fears that Uhuru's continued silence could undermine fight against corruption.
"It is sad that the country can be rocked in a series of earthquake scandals yet the president is silent over the matter," Tiren said.
On his part, Keter said: "All we want now is action. Uhuru should send Kiunjuri packing. We can sit and watch our farmers lose billions."
However, Kiunjuri has dismissed the claims insisting that no money was lost and that the country only 'lost opportunity'.
Both Tiren and Keter have been leading onslaught against Jubilee and the latter has even been seen openly courting Baringo Senator Gideon Moi.
