The George Zimmerman trial in the killing of Trayvon Martin continues today. Watch the live video below.

A prosecution witness, Martin’s friend Rachel Jeantel, took the stand today, recounting the phone call she had with him while he walked back from the store just before the confrontation with Zimmerman.

Defense attorney Don West “pressed her on what he indicated were inconsistencies between the letter and Jeantel's subsequent depositions and testimony -- in particular her recent revelation that Martin told her he was being followed by a ‘creepy-ass cracker,’” writes Fox News.

“He started walking then noticed someone was following him," Jeantel said, reading from a letter send to Martin’s parents after the killing. "Then he decided to find a shortcut cause the man wouldn't follow him. Then he said the man didn't follow him again. Then he looked back and saw the man again. The man started getting closer. Then Trevon turned around and said Why are you following me!! Then I heard him fall. Then the phone hung up. I called back and got no response. In my mind I thought it was just a fight. Then I found out this tragic story. Thank you.”

There are some potential inconsistencies in Jeantel’s testimony that the defense hopes to focus on.

“Jeantel's testimony is key to the prosecution's argument that Zimmerman was the aggressor in the fatal confrontation. West tried repeatedly to chip away at Jeantel's testimony, including in one heated exchange over whether Martin would have told Jeantel if he had decided to start a fight with Zimmerman,” according to Fox.

Zimmerman faces life in prison if he is convicted.
