The preliminary hearing for Charlie Kirk‘s suspected assassin, Tyler Robinson, is set to begin Monday, with prosecutors pushing for Robinson to be tried for Kirk’s murder as the family of the late conservative activist sits in the courtroom.

The hearing is a preliminary measure where the prosecutors will bring evidence forward to make their argument that the case should head to a jury trial for murder. Prosecutors are seeking the death penalty for Robinson, as he faces seven felony charges related to his suspected crime.
