The Simams presented themselves to court after an anti-graft court on Thursday ordered their arrest over the graft claims.
The anti-corruption court in Eldoret issued a warrant of arrest after the two and four others failed to honour summons to appear before the Ethics and Anti Corruption Commission office in Eldoret to shed light on the road tender scam.
They were charged with three counts which included awarding of a contract to Kachur Holdings, a company that did not qualify for construction of roads.
Kimeli is a director in Kachur Holding.
They faced a second charge of fraudulently acquiring public money amounting to Sh1.9 million from the Rural Roads Authority to pay for services that have not been sufficiently completed.
And, a third charge of fraudulently acquiring public funds from the RRA amounting to Sh2.5 million to pay for a service that had not been sufficiently completed.
They were released on a bond of Sh1 million each and a surety of half a million shilling each.
The case will be mentioned on July 23.
In a report to Parliament, the commission wanted them charged over a case in which the Kenya Rural Roads Authority irregularly awarded a road repair tender to a company the MP owns.
The commission said investigations established that procurement laws were flouted in tender for the improvement of the Bayete – Chuiyat – Bargeiywa road in her constituency.
