The Latest: Protesters vow to keep pressure on Cecil the lion's killer

The number of protesters outside Walter Palmer's clinic in Bloomington grew to nearly a dozen by midmorning Tuesday. Just two or three were on site earlier in the day when Palmer returned to work after spending weeks out of the public eye.

Palmer has been the focus of international scrutiny since he was identified as the hunter who killed Cecil in Zimbabwe in July.

The group held signs calling for the extradition of Palmer, chanting: "We will not falter! Prosecute Walter!"
