The states of Oregon, Pennsylvania, Tennessee and Texas are challenging RadioShack for trying to sell customers' personal information.
If Radioshack sold data on customer activity, the company would violate the Texas Deceptive Trade Practices Act, according to an objection filed Friday in Radioshack's Delaware Chapter 11 case.
Oregon and Pennsylvania joined Texas in the objection Wednesday, following the lead of Tennessee, which joined Monday. All states cited violations of their own consumer protection laws. Texas also submitted letters of support from attorney general's offices in other states, including Maryland, Colorado, Nevada, District of Columbia, Illinois, Iowa, Nebraska, Washington, Wisconsin, Arkansas, Connecticut, Florida, Hawaii, Indiana, Kentucky, Maine, Nebraska and South Carolina.
The Texas objection states that 117 million customers would be affected by the data sale, by its own calculation. Radioshack declined CNBC's request to confirm the number or comment on the case.
Radioshack is currently considering bids to repay its creditors as part of the Chapter 11 case. Some Radioshack stores will be owned by Standard General and Gamestop, though commercial finance and asset management company Salus Capital Partners is also vying to liquidate the firm, according to .
