I posted in another thread that the object people thought came out of Hillary’s pant leg was likely an empty glass cartridge from an injector pen (Apokyn pen) for apomorphine, a fast-acting dopamine agonist used with Parkinson’s patients, and that the doctor dropped it on the ground and tried to kick it away but it ended up hitting Hillary in the leg.
Yep, I spotted it too; go to 5:33 in the video I linked to here:
