evidence: That's despite claims from University of Texas researchers that about 1.4 million PPP loans show signs of possible fraud, like suspiciously high payrolls and multiple businesses listed at the same residential address. The SBA disputes these findings, but its own inspector general has estimated that at least 70,000 loans were potentially fraudulent. Meanwhile, the SBA is closely scrutinizing just a tiny portion of the millions of PPP loans for fraud and forgiveness eligibility. The SBA uses computer models to review all 11.4 million loans, according to Patrick Kelley, a senior official with the agency, but he says auditors have manually reviewed only about 215,000 loans, or roughly 2% of the total number issued. [...] About 1 million of the 11.4 million PPP loans remain unforgiven. The majority of these unforgiven loans are held by sole proprietors and independent contractors: one-person businesses specifically targeted by a later round of the program. Many work in service jobs heavily impacted by COVID-19, such as barbers, janitors and Uber drivers.
