Schwartz, Laxalt's opponent in the Republican primary election, says the attorney general has shown he cannot separate his official duties and his campaign.
Laxalt came under fire after the Reno Gazette-Journal published an audio recording where Laxalt is suggesting his staffers help beat back a news story critical of him for casting the lone dissenting vote in the pardon of a convicted murderer.
The recording suggests he has used his state staff for political purposes.
In an interview with the Las Vegas Review-Journal, Schwartz also cited three past moves by Laxalt tied with big campaign contributions.
Laxalt's campaign spokesman Andy Matthews called Schwartz's efforts a "laughable political stunt" in a Friday statement.
