From Bearing Arms:

The Justice Department submitted a new blueprint today to define more clearly who must secure a federal firearms license for legal secondary market transactions. This new framework would redefine who is required to obtain a federal firearms license to sell guns legally. This license mandates that a dealer run background checks on buyers, among other things.

The proposal represents the latest effort by the Biden Administration to strengthen gun control via administrative rules. With the exception of the Bipartisan Safer Communities Act, Biden has not had Congressional support for his gun control agenda. So the President has sought to enact changes through federal rulemaking by the Department of Justice (DOJ) and the Bureau of Alcohol Tobacco and Firearms (ATF).
