According to Defence Cabinet Secretary Aden Duale, former President Uhuru Kenyatta he presided over plundering, extrajudicial executions, and misrule during his ten-year reign.
Duale, a close supporter of President William Ruto, has also recommended that retired presidents stay out of politics, as Mwai Kibaki and Daniel Moi did.
"It's appalling the depths to which the former president has fallen, to the extent that he rudely castigates police officers on official duty protecting life and property," Duale said on his social media platforms.
"It is sad to see a former President degrade his stature after completing two full terms by fighting for a shell of a party that oversaw over misrule, wanton looting of government coffers, and extrajudicial killings during the notorious rogue handshake regime."

Duale also chastised the previous President for fighting for a "shell of a party."
"The once-dominant party, with a near-supermajority of 174 lawmakers, now has a paltry number who have switched their allegiance." Uhuru should stop tainting his reputation by attempting to resurrect a dormant party and leave the dispute to elected legislators."
The high-ranking government official in the military also took issue with the former President's remarks on the police.
"Kenyans are watching and will not tolerate further economic sabotage and violence perpetrated by self-serving leaders," he continued.
The deadlock between Duale and Kenyatta comes after Mr Kenyatta stormed the Jubilee party premises and sided with opposing groups.
According to a recent TIFA poll, at least 59% of Kenyans want former President Uhuru Kenyatta to quit politics and enjoy his retirement. In comparison, 36% want him to stay politically engaged and back candidates and ideas with which he agrees.
