Five months into his second term as Vice-Governor, Lagman assumed the governorship by operation of law on December 1, 2022.

In February 2024, Alwin Nimo, a former chairman of Barangay Anislag, Daraga, alleged that Lagman had received bribes from illegal gambling (jueteng) bosses in the province when he was vice governor and filed a complaint against the latter for graft and corruption at the Office of the Ombudsman. Lagman denied the accusations, calling it "driven by political motives." In October 2024, the Ombudsman imposed a preventive suspension on Lagman as part of its investigation into the charges.
