Former Environmental Protection Agency Administrator Lisa Jackson will testify before House Republicans who allege that she shielded agency business from public view by using secondary and perhaps personal email accounts.

Jackson, now a top environmental official at the tech giant Apple, is among the current and former federal officials slated to appear at the Sept. 10 House Oversight and Government Reform Committee hearing titled “Preventing Violations of Federal Transparency Laws.”

“Officials in multiple Administrations have struggled to fully comply, and in some instances willfully flaunted, federal transparency and record keeping laws through their use of non-official e-mail and other electronic communications to conduct official government business,” committee Chairman Darrell Issa (R-Calif.) said in a statement announcing the hearing.

Jackson’s attorney confirmed her appearance. “She looks forward to offering her testimony and addressing any questions that the Committee wishes to put to her,” attorney Barry Coburn said in an email to The Hill Thursday.
