They claim he was "demonized" during Steven Hayes trial.
His attorneys claim he get a fair trial in New Haven because he had been so "demonized" during the trial of co-defendant, Steven Hayes.
Komisarjevsky is the second man to be charged in the Cheshire home invasion and slayings of Jennifer Hawke-Petit and her daughters, Hayley and Michaela.
Prosecutors have objected, saying extensive media coverage does not prove prejudicial publicity.
The case will be back in New Haven Superior Court on Wednesday.
Hayes was condemned to death in November.
Jury selection for Komisarjevsky's trial starts March 14.
