House Republicans are asking the Election Assistance Commission to turn over the details of a settlement it reached with a Republican lawyer in a political discrimination case.

In a letter Wednesday, House Administration ranking member Dan Lungren (R-Calif.) asked the EAC to provide the panel with a copy of a confidential settlement agreement and other evidence that could dispel recent claims by federal investigators. In its findings, the U.S. Office of Special Counsel claimed that Democratic commissioners Gracia Hillman and Rosemary Rodriguez held up the hiring of an unnamed GOP lawyer because of his political affiliation.

This week’s letter follows recent demands for Hillman’s resignation by Lungren and Reps. Kevin McCarthy (R-Calif.) and Gregg Harper (R-Miss.) over the OSC’s conclusions in the case.

Rodriguez no longer works at the commission. McCarthy and Harper also were co-signers on Wednesday’s letter.
