The attorney for an Ohio man accused of plotting to attack the U.S. Capitol building is asking a federal judge to allow the man a private review of video and audio files in the case against him.

The assistant federal public defender representing 21-year-old Christopher Lee Cornell says in a motion filed Monday that having an attorney present while he reviews "the massive amount of electronic material" isn't practical. Karen Savir says Cornell can use a jail computer set up without Internet access to review the files over a five-day period.

Her motion says prosecutors are OK with that arrangement as long as he doesn't have access to outgoing mail.

Cornell has pleaded not guilty to attempted murder of U.S. officials and employees and two other counts.
