The Combined Investigation Headquarters, which is investigating allegations of collusion between religion and politics, summoned Jeong Won-ju, the former secretary-general of the Unification Church, for questioning regarding accusations of delivering money to politicians. The investigation, headed by Chief Prosecutor Kim Tae-hoon, is taking place at the Seoul High Prosecutors' Office. This is the second interrogation after one conducted on September 23, indicating a deepening inquiry into the Unification Church's financial dealings with political figures.

Jeong is suspected of being involved in the Unification Church's financial contributions to political actors, particularly relating to claims made by former Unification Church head Yun Young-ho during a special prosecutor's investigation. Yun mentioned that Jeong had potentially delivered millions of won in bribes to various politicians, including members of the Democratic Party and former lawmakers of the opposition. As the investigation continues, the authorities aim to clarify Jeong's role in these alleged transactions.

In addition to these bribery allegations, Jeong is also facing scrutiny over claims related to 'splitting donations' to politicians, where smaller amounts are given to bypass regulations on political funding. In 2019, an individual associated with the church was reported to have divided a significant donation among multiple politicians, raising concerns about further breaches of political funding laws. The investigation's ramifications could potentially involve other high-ranking officials of the church, as the authorities pursue any collaborative wrongdoing linked to Jeong and others involved in the Unification Church's political financial activities.
