In the
2019 general election, Masondo was elected to a seat in the
National Assembly, the lower house of the
South African Parliament. He was ranked 19th on the ANC's national party list. The
Mail & Guardian surmised that he was "set to be groomed to take over the running of
the treasury". He was characterised variously as "a rising star"; as "arguably the most promising member of the ANC's younger generation"; and, by
Richard Calland, as "young, intellectual, energetic, and one of the few ANC politicians around who still care about policy debate and ideas". In his capacity as deputy minister, Masondo was appointed to chair the
Public Investment Corporation in November 2021. Mboweni also appointed him to lead the ministry's pro-growth structural economic reform programme, which the
Business Day viewed as a wise choice because of Masondo's closeness to
the left. It later emerged, through reporting by
amaBhungane, that Masondo had offered money to Lebitse in exchange for "peace"; according to Lebitse, Masondo had pressured her to abort a pregnancy in January 2019, and she in turn had pressured him to allow "dialogue" between their families about payment of damages. During a subsequent investigation by the
Commission for Gender Equality, Masondo admitted to having had protected sex with Lebitse on one occasion but said that they had not been in a romantic relationship, that he was not responsible for her pregnancy, and that he had not encouraged her to have an abortion. In any case, in February 2020, the
National Prosecuting Authority declined to prosecute Lebitse on extortion charges. However, Lebitse pursued a civil lawsuit against Masondo, the head of the Hawks, and the Police Minister
Bheki Cele, alleging that Masondo had abused state resources and his own political influence in order to effect her arrest, which she said had been unlawful. Masondo approached the ANC's Integrity Commission to seek advice on his response. In July 2020, the commission recommended that Masondo should step aside, with commission chairperson
George Mashamba writing: Your actions have brought disrepute to the organisation, but in acknowledging this and taking responsibility, you have shown commitment to the organisation and the ideals we strive to reach. We have confidence that lessons have been learnt from the ordeal you are going through. We accept that your lawyers have advised you to report the matter to the Hawks and that you acted on their advice. However, we think that you showed poor judgment and that you should have known that involving the Hawks in a domestic matter would open you up to accusations that you were abusing your power and your access to state resources. Masondo said he was surprised by the commission's recommendation, He was returned to the Central Committee when he was elected, unopposed, to succeed
Chris Matlhako as second deputy general secretary of the party; he serves alongside first deputy secretary
Madala Masuku and under general secretary
Solly Mapaila. He performed poorly in the nominations stage of the contest, and he was expected to split the vote with Mantashe; both were viewed as supporters of President Ramaphosa. When the ANC's
55th National Conference was held in December, Masondo lost resolutely in the chairmanship race; he received only 282 votes against Mantashe's 2,062 and
Stan Mathabatha's 2,018. However, he was re-elected to the ANC National Executive Committee; he received 1,304 votes across roughly 4,000 ballots, ranking him 41st in the 80-member committee. As of 2023, he also remained the principal of the O. R. Tambo School. == Personal life ==
