马哈迪·莫哈末
In 2020 Malaysian political crisis, Baru with 10 other PKR MPs lead by Mohamed Azmin Ali decided to leave the party to support Malaysian United Indigenous Party (BERSATU) Prime Minister candidate Mahathir Mohamad to remain as the Prime Minister. However, after Mahathir Mohamad refused to return as Prime Minister, BERSATU nominated Muhyiddin Yassin as the nominee for the Prime Minister position. After PH changed their support from Anwar Ibrahim to Mahathir Mohamad as Prime Minister, he and Jonathan Yasin who were two of the 11 MPs who left PKR came back to support Mahathir Mohamad as the Prime Minister rather than Muhyiddin Yassin. In the aftermath, Baru had finally chose to join the Sarawak-based United Sarawak Party (PSB) on 30 May 2020.
