University lecturer Prof Edward Kisiang'ani has criticised those faulting the move by the United States, to ban Busia Senator Amos Wako from setting foot on it's soil.
Through Secretary of State Michael Pompeo, the President Donald Trump-led government accused Wako of being involved in corruption and failing to prosecute individuals suspected of graft, and declared he will never be allowed to enter the populous nation.
The travel ban also includes Wako's wife Flora Ngaira and son Julius Wako.
Kisiang'ani dismissed claims Kenya was left in the dark over Wako's ban, saying US was very clear on its move and speculated that President Uhuru Kenyatta's government had been informed.
"In this Wako matter, some guys here are making strange jokes and comments. The U.S government does not operate the way some Africa governments do. The US government cross-checks its facts before making an official statement on any matter. Make no mistake about that!" the university don tweeted on Wednesday night.
"The US intelligence system is top notch. You can't compare it with ours. Am sure that before Secretary of state Pompeo made the announcement on Wako, the Kenya government was fully briefed. Our government already knows the facts of this case. So please stop defending what you don't know!" he added.
On his part, Wako said the US should come out to give evidence on claims he was involved in corrupt actions.
In a press conference on Wednesday in Parliament Buildings, the second-time legislator said his wife and son should not be linked to his problems, since he has been serving in public offices as an independent person.
"I was baffled when out of the blue, without any notification whatsoever, or without being given the fundamental right of being heard on any allegation against me... I’m therefore entitled to ask where has the utter commitment to the protection of human rights, rule of law and constitutionalism gone in the United States of America?" Wako posed in a statement posted on his Facebook page.
