After taking his seat in the Senate in May 2007 Agbo was appointed to committees on National Identity Card & Population, Housing, Federal Capital Territory and Drugs Narcotics Anti Corruption. In April 2008 he was appointed vice-chairman of a committee investigating Mallam Nasir el-Rufai's administration of the FCT. In a mid-term evaluation of Senators in May 2009, This Day noted that he had sponsored bills on the Nigerian Congressional Medal of Honour Award, the National Cooperative Society Federation and the Nigerian Unified Filed Institute, and had sponsored or co-sponsored many motions. He was active in plenary and committee work.
Agbo has canvassed for establishment of a Ministry for the disabled. In an interview in March 2009, speaking of Nigeria in general and Abuja FCT in particular, he said that the program to rebrand Nigeria would not work until the place was indeed an attractive place to visit, with good infrastructure, a clean environment and security. In July 2009 he called for establishment of anti-corruption personnel in Nigerian embassies across the world to detect corrupt practices, working closely with foreign agencies.
