Adeseun noted a wide discrepancy between claims of implementation rate between the legislature and the executive.

Speaking in March 2011, Adeseun said that the Appropriation Bill 2011 had been passed out of the national interest, citing intense pressure from the Executive, despite the initial refusal by the House since some agencies had failed to present their budgets.

Senate Adeseun was elected to the Senate in 2011, assuming his seat on 29 May 2011. He is the Chairman of the Capital Markets Committee and a member of the Solid Minerals Committee.

In October 2012, as the Capital Markets chairman, Adeseun urged President Goodluck Jonathan to remove Arunma Oteh from her position as Director-General of the Security and Exchange Commission, calling his choice to reinstate her "a flagrant disregard of the resolution of the House of Representatives."

In February 2026, Adeseun, described in press coverage as an All Progressives Congress chieftain in Oyo State, explained that his advocacy for a federal polytechnic in Ayede, in Ogo-Oluwa Local Government Area, Oyo State, was driven by a Federal Ministry of Education study that found Oyo State had only one federal tertiary institution, the University of Ibadan, unlike other states with two or three. Adeseun said the project did not materialise during his first term in the National Assembly but that he continued pushing for it, and that his background in urban and regional planning informed his choice of Ayede as the site. He also welcomed a Federal Government policy allowing polytechnics to award degrees, calling it a reform that would remove the disparity between HND holders and university graduates and encourage more students to pursue technical education.
