A dramatic confrontation is unfolding between State House Director of Communications Bonny Musambi and Kamba urban music artist and cancer awareness activist Biez Kaviru after the government official demanded a public apology over allegations that he blocked a cancer petition meant for President William Ruto.
Speaking in an exclusive interview with a local FM station, Musambi—who is also an aspiring Kitui Central MP on a UDA ticket—firmly denied claims that he prevented Kaviru from delivering a petition urging the government to declare cancer a national disaster.
Musambi challenged the artist to either produce recorded evidence or publicly retract the allegations.

“I demand an apology from Biez Kaviru for whatever he has said about calling me. If not, he should produce recorded evidence of me telling him never to call when the President is in Kenya,” Musambi said.
According to the State House communications director, he never had the alleged phone conversation with the artist and never attempted to block his mission.
Musambi explained that the only contact related to the matter came when he received a call from someone inquiring about Kaviru’s campaign while he was on his way to a media interview.
Kaviru’s Claims After Kitui–Nairobi Awareness Walk
The controversy stems from remarks made by Biez Kaviru, who recently accused Musambi of being the main barrier that stopped him and his team from presenting their petition to the President.

Kaviru had embarked on a high-profile awareness campaign, walking from Kitui to Nairobi to draw attention to the cancer crisis and push for national recognition of the disease as a disaster.
During the interview, the artist claimed Musambi had initially supported his campaign before allegedly warning him not to contact him when the President was in the country.
“Bonnie Musambi called me and told me never to call him when the president is in Kenya. If I ever called, I should make sure the president is out of the country,” Kaviru alleged.

Kaviru also accused Musambi of denying knowledge of his campaign despite having publicly commented earlier that he would support the delivery of the petition.
Senator Tabitha Mutinda Introduces New Twist
The controversy has taken another dramatic turn after Tabitha Mutinda weighed in on the matter while speaking to a local YouTuber.
According to the senator, the process of delivering Kaviru’s petition allegedly ran into security concerns after members of his entourage were flagged by authorities.

Tabitha Mutinda speaks during an interview on Rick B’s YouTube show, where she claimed security concerns involving individuals accompanying cancer awareness activist Biez Kaviru disrupted the process of delivering a petition to President William Ruto.
“Kitu moja iliharibu process ya Kaviru ya kuleta barua hadi wakasimamishwa pale Mombasa Road ni kwamba waliungana na watu wanne ambao sifa zao kwa kitengo cha usalama ni mbaya. Kwanza mmoja wao alisimamishwa katika kitengo cha polisi,” Mutinda said.
Her remarks suggest that security agencies may have intervened due to concerns about individuals accompanying the activist, potentially complicating his mission to deliver the petition.
However, Kaviru has previously dismissed claims that his team was teargassed along Mombasa Road, insisting that the incident never occurred.
Political and Public Debate Intensifies
The unfolding dispute has triggered intense debate across radio stations, YouTube platforms and social media, with supporters of both sides questioning what really happened during the activist’s journey to Nairobi.
Kaviru has maintained that his mission was purely about raising cancer awareness and delivering a petition to the President, while Musambi insists he played no role in blocking the initiative.

Meanwhile, Kaviru acknowledged the support of Mwengi Mutuse, whom he credited for providing security during parts of the campaign.
With Musambi now demanding evidence or an apology, attention has shifted to whether the artist will release the recording he claims exists—a move that could dramatically escalate the already explosive controversy.
