When he was elected as a member of parliament in 2016, he was arrested due to a corruption scandal.[1] At the first trial, he was sentenced a penalty for 700,000 won.[2] He then, was appealed for high court by the attorney, although the result was same.[3] On the other hand, as those who're sentenced less than 1 million won can continue their positions, he had no problem to keep his membership.
On 2 May 2017, 14 members of the Bareun Party declared that they would return to Liberty Korea Party (formerly Saenuri Party) and support Hong Jun-pyo as the future president, rather than Yoo Seong-min.[4] Hwang was one of them, however, suddenly cancelled the returning.[5] The reason was that the returning of them was strongly opposed by pro-Parks in LKP.
However, later than, he spoke up to combine Bareun with LKP, and finally returned to LKP on the November of the year.[6]
