FORT MEADE, Maryland (Reuters) - A U.S. military judge on Tuesday denied a defense request to dismiss the case against Army Private First Class Bradley Manning in the mass disclosure of military and diplomatic secrets by WikiLeaks.

Manning's lawyers filed a motion to dismiss all charges against him, arguing the government had violated their client's right to a speedy trial.

Ruling at a pretrial hearing on Tuesday, military judge Colonel Denise Lind said that the case took only 90 days to come to trial, well within the 120 day "clock" rule that exists for a court martial in reference to the time between pretrial confinement and arraignment.

Manning is accused of releasing hundreds of thousands of classified documents, including U.S. diplomatic cables and various military reports. He has been jailed for over 1,000 days.
