Nyandarua Senator John Methu has said that he was offered Ksh50 million as part of a political effort to impeach former Deputy President Rigathi Gachagua.

Methu detailed how he claims unnamed political actors tried to sway him during the debate over Gachagua’s impeachment, a move that he says revealed widespread political influence in government.

Speaking in an interview with Kameme FM on Monday, February 27, 2026, Methu claims the alleged bribe was offered in exchange for his support for the impeachment against Gachagua.

“I was promised Ksh50M during Rigathi’s impeachment as deputy president,” Methu said.

The lawmaker has added that the approach was coupled with political persuasion and pressure, seeking to influence key leaders to take a government-friendly stance. But Methu says he spurned the alleged offer, asserting that his actions were driven by conviction, not political expediency.

Methu, who has emerged as a top supporter of former Deputy President Rigathi Gachagua, has argued that the political process that led to his dismissal was more about factional politics than effective governance. He claimed that Gachagua was being ostracised, although he was instrumental in the formation of the Kenya Kwanza government.
