Wanga said NCIC seems to returning the dark past os summoning political leaders to cover up offenses.
"If this is the case, I am even more worried of the country ahead of 2022," she added.
On Friday, Kakamega Senator Cleophas Malala and Wanga and Aisha Jumwa were among 10 lawmakers who were summoned by NCIC for questioning over the violence that rocked last Thursday’s by-elections across the country.
Others are MPs Faisal Bader (Msambweni), John Waluke (Sirisia), Ben Washiali (Mumias East), Chris Wamalwa (Kiminini), Charles Were (Kasipul), Fred Kapondi (Mt Elgon) and Nominated Senator Millicent Omanga.
NCIC chairman Samuel Kobia on Saturday said the legislators are expected to appear before the commission on Monday to shed light on the roles they played during the chaos witnessed during the elections.
Kobia said the summons do not just indicate the commission's intention to investigate and prosecute the lawmakers but also the plan to stop those exhibiting unethical conduct from occupying public office.
