Eichorn, scheduled to make his first court appearance today, has not commented on the allegations or calls to resign.
Zoom in: The federal complaint alleges the 40-year-old senator responded to an online prostitution ad and texted with an undercover officer posing as a 17-year-old girl for several days before arranging to meet for a paid sexual encounter.
He arrived at the designated meeting location with cash and an unopened condom in his truck, prosecutors allege.
What we're watching: Senate Republicans say they'll make a motion today to expel Eichorn from the chamber, which Democrats control 34-33.
