An immigrant charged in the fatal stabbing of an Iowa college student has hired new defense lawyers.

Attorneys Chad and Jennifer Frese filed paperwork Sunday to represent Cristhian Bahena Rivera, who is accused in the killing of 20-year-old Mollie Tibbetts.

They’re expected to replace attorney Allan Richards, who called President Trump "sad and sorry" for labeling his client guilty before trial.

Rivera, a dairy worker suspected of being in the U.S. illegally, was charged with murder last week.

Richards says Rivera’s family hired him and that he hasn’t spoken with Rivera about being replaced.

Richards says he understands if Rivera wants attorneys with more criminal trial experience.

Jennifer Frese confirmed Monday that the two have been privately retained to represent Rivera.
