Jose Canseco accused Mark McGwire of calling him a liar Tuesday and said the disgraced slugger was not being entirely truthful and upfront when he admitted Monday to steroid use.

Speaking on "The Waddle & Silvy Show" on WMVP-AM 1000, Canseco took McGwire to task for denying Canseco's claim that they injected each other with steroids in clubhouse bathroom stalls when they were on the Oakland Athletics from 1986-92.
