Konnech, which is based in Michigan, develops software to manage election logistics, like scheduling poll workers. Los Angeles County is among its customers.

The company has been accused by groups challenging the validity of the 2020 presidential election with storing information about poll workers on servers in China. The company has repeatedly denied keeping data outside the United States.

Mr. Gascón’s office said its investigators had found data stored in China. Holding the data there would violate Konnech’s contract with the county.
