[3] On 17 November 2021, Rayer claimed that there was a video on social media allegedly showing Najib signing his autograph on a motorcycle while campaigning in the state polls.

He offered to provide the video to Khairy, urging that action be taken against Najib for repeatedly flouting standard operating procedures (SOP).

[4] During the Debate on Budget 2022 at the Committee Stage, Rayer had asked Finance Minister Tengku Zafrul Aziz why Najib has yet to be blacklisted by the Inland Revenue Board (IRB) and allowed to travel to Singapore despite the outstanding tax arrears owed to the government.

[13] On 5 August 2018, DAP's RSN Rayer, sparked controversy in the Dewan Rakyat when he used the insult ‘kepala bapak’ during the sitting.

Hamzah had criticised Rayer for trying to ask Deputy International Trade and Industry Minister Dr Ong Kian Ming whether the 1Malaysia Development Bhd (1MDB) issue had triggered outflow of foreign investments from Malaysia.

On that meeting, he was raising an additional request to the Deputy Home Affairs Minister Azis Jamman, over the poor conditions spreading within police barracks in Penang.

He then criticized on how the previous Barisan Nasional government failed to assist in upgrading those damaged or poorly built police barracks, pointing out that their reason of not doing so as a result of not having the enough financial resources is pointless as former Prime Minister Najib Razak's wife, Rosmah Mansor, was able to freely import jewelries into the country without even paying GST.
