Katie Couric told HuffPost Live on Thursday that she did not know Alex Rodriguez was lying when he denied ever using steroids during their 2007 interview.

The Yankees player admitted in 2009 to using steroids from 2001 to 2003, but has maintained that he has not used any since then. In recent days, however, he has found himself at the center of another scandal involving performance-enhancing drugs, and could be one of twenty players suspended for allegedly using PEDs.

Couric interviewed him for "60 Minutes" in 2007, when he told her that he had never used performance-enhancing drugs before. She said Thursday that "no one knows for sure" whether Rodriguez is telling the truth now.

When asked if she had any inclination that he had been lying during their interview, she said, "Unfortunately, I'm one of those people who really sees the good in people and wants to believe that people are telling the truth." She added that he wrote her an apology after confessing to steroid use.

In his confession to ESPN years ago, Rodriguez addressed his interview with Couric, saying that "at the time, Peter, I wasn't even being truthful with myself. How am I going to be truthful with Katie or CBS?"
