The U.S. Justice Department is resisting an effort in court that would force the U.S. Treasury Department and Small Business Administration to reveal the names of millions of companies and individuals who received federally backed coronavirus relief loans valued at less than $150,000.

Under pressure from news organizations and others, the SBA and Treasury last month released the identities of companies that sought and received Paycheck Protection Program loans valued at between $150,000 and $10 million, the maximum under the relief program helping companies cover certain workforce costs associated with the pandemic. For each company name, the government only released a loan range—for instance, $5 million to $10 million.
