House Oversight Committee Chairman Rep. James Comer, R-Ky., announced Tuesday plans to hold a hearing next week on the impeachment inquiry into President Joe Biden, the first hearing of its kind since Republicans launched the inquiry last week.

The hearing, which will take place Sept. 28, will examine the “constitutional and legal questions surrounding the President’s involvement in corruption and abuse of public office,” a committee spokesperson said.

Comer also plans to subpoena bank records of the president’s son and brother, Hunter and James Biden, “as early as this week,” the spokesperson said.

Comer, who has been leading the investigation into allegations Joe Biden was inappropriately involved in his son’s business dealings, has subpoenaed a number of banks and received thousands of bank records in response, but these forthcoming subpoenas will mark the first time Comer has subpoenaed records of the president’s immediate family.

“The Oversight Committee will continue to follow the evidence and money trail to provide the transparency and accountability that Americans demand from their government,” the spokesperson said.
