[1] In the late 1970s, Wabara worked at the Nigerian Embassy in London as an External Affairs Officer till his transfer to Chad as the Head of Chancery in 1984.

The historic economic crises that swept throughout Nigeria in the 1980s took a toll on his businesses, and subsequently, Wabara worked as the Assistant General Manager Apapa Trawlers, a subsidiary of the Ibru Organization from 1985 to 1989.

With the formation of the National Republican Convention by the Ibrahim Babangida regime, Wabara saw a platform to be of service to the people of Ukwa East Local Government Area, Abia State.

Wabara's tenure in the House of Representatives, like those of his colleagues, was cut short in 1993 when the famous "12 June" political crisis erupted in Nigeria.

The Presidential elections, which had been won by SDP candidate, Chief M.K.O Abiola had been nullified by the Ibrahim Babangida Regime, heralding political tensions and unrest.

After a stint in New York, Wabara was appointed as a councilor in the Ukwa East Local Government Council, affording him a chance to serve at the grassroots.

One year after, he contested in the 1999 Senatorial Elections and won the mandate to represent Abia South District in the Nigerian Senate of the 4th Republic.

By the early 2000s, renovation of army barracks, promotion of qualified officers who had long been overlooked, reformation of the security system were achievements of the Wabara-led Senate Committees.

[4] In 2003, Adolphus Wabara won the PDP Senatorial primaries against Chief Emeka Wogu and proceeded to contest for reelection into the Nigerian Senate for Abia South.

As a leader of the Nigerian Senate, Wabara was committed to service to the people of Nigeria by ensuring the cooperation of the legislative and executive arms of government.

On 22 March 2005, the National Television Authority (NTA) broadcast a report by President Olusegun Obasanjo, publicly indicting Wabara for involvement in a bribery scandal to the tune of 55 million naira ($400,000).

This announcement was made without the constituted legal procedure, leading to a saga of events that culminated in Wabara's resignation from the office of the Senate President.

Osuji allegedly bribed Wabara in exchange for the Senate’s approval of an inflated budget and was immediately dismissed from his position by President Obasanjo.

[7] Following his resignation from Senate Presidency, Wabara, with Osuji and five others were arraigned before the Federal High Court, Abuja on 12 April 2005 by the Independent Corrupt Practices Commission (ICPC).

The court held that the action of the federal government on the allegation was most embarrassing, barbaric, and uncivilised because the accused persons had not made statements to any security agents before the broadcast trial and finally pronounced guilty.

As there was not sufficient evidence to prosecute the charge, the defendants, including Wabara, were discharged under section 355 of the Administration of Criminal Justice Act 2015 which states: "Where a complainant at any time before a final order is made in a case satisfies the court that there is sufficient ground for permitting him to withdraw his complaint, the court may permit him to withdraw the complaint and shall thereupon acquit the defendant.

Despite these strides, a politically motivated dissolution of the Governing Council was carried out on 20 March 2022 after Adolphus made a comment that "PDP will lose Abia if the 2023 Governorship position is zoned to Ngwa".
