House Republicans reopened the partisan battle over the Jan. 6, 2021, Capitol attack on Wednesday, launching a new subcommittee aimed at reexamining security failures and federal law enforcement decisions that Democrats argue were already settled.

The Select Subcommittee to Investigate the Remaining Questions Surrounding January 6 held its first hearing, marking the GOP’s effort to reexamine years of criticism of the Biden Justice Department, the FBI, and the now-defunct Democratic-led Jan. 6 select committee. The panel is chaired by Rep. Barry Loudermilk (R-GA), who has spent years investigating the original investigation and its omissions.
