Sentencing Commission is obliged to increase sentences for those defendants under a provision of the Bipartisan Safer Communities Act, the major gun safety measure that President Joe Biden signed into law in June.
The commission, which has seven voting members, in January proposed two options to increase penalties, by either allowing judges to enhance sentences for straw purchasers or amending the federal sentencing guidelines to increase the starting, or base, range for sentences.
"A knee jerk response to the directive in the Bipartisan Safer Communities Act will not make us safer," she said in a testimony at the hearing, arguing policy makers should collect data first before adopting any measure.
The panel faces a May 1 deadline to submit any amendments to the guidelines to Congress.
