Kenneth Lester, the judge handling George Zimmerman's second-degree murder case, will not recuse himself.

Zimmerman's attorneys filed a motion asking Lester to remove himself, claiming the judge was biased against Zimmerman.

But in a ruling released today, Lester said he found the allegations in the motion filed by the attorneys to be "legally insufficient."

George Zimmerman is on trial for the death of Trayvon Martin back in February.

Zimmerman's attorneys filed the motion to have Lester removed earlier this month. The motion stems from Lester's decision to revoke Zimmerman's $150,000 bond after it was revealed that he had more money from donations than originally disclosed.

Lester later granted Zimmerman a $1 million bond, and in that ruling made several comments about Zimmerman's character, and even hinting at future contempt proceedings.

George Zimmerman's attorneys say those comments, plus the judge's decision not to weigh evidence of Zimmerman's innocence when determining how to set bond, show Lester is not capable of impartiality in the case.

In Lester's ruling today, however, the judge said Zimmerman's attorneys had to prove "legal sufficiency."

"For purposes of determining legal sufficiency, the Court must assume all of the factual allegations supporting the motion are true... The Court is not permitted to deny the allegations supporting the motion as untrue, reject them as unfounded, or comment upon them at all. To do so establishes independent grounds for disqualification.

"Therefore, as required by law, the Court assumes the factual allegations supporting the motion for disqualification are true solely for the purpose of determining legal sufficiency. With that standard in mind, the Court finds the motion to be legally insufficient."

Zimmerman claims he was acting in self-defense when he killed Trayvon Martin, following a struggle.
