Mitchell Kusick, 20, was denied bond during a hearing Monday afternoon.
His attorney, Marci Gilligan, argued that he was not a danger to the public and that he had voluntarily sought mental-heath help. She also said had recently been prescribed different medication for bipolar disorder. Gilligan did not say what the new medication is, but said Kusick had been taking Prozac.
Federal prosecutor Richard Hosley argued Kusick could decide to harm children at any time if he were not locked up in jail.
Kusick called Secret Service Special Agent Melissa Blake who testified that police found magazines and books about assassinations inside Kusick's home.
After a hearing that lasted more than an hour, federal Magistrate Judge Kristen L. Mix ruled there was no way to assure the public's safety if Kusick was released on bond.
Mix also ruled that the government had shown that there was enough evidence against Kusick for the case to proceed forward.
If convicted, Kusick could get five years in a federal prison. Considering he has no past arrest history, that is unlikely, experts tell the 9Wants to Know investigators.
Kusick is also facing a state misdemeanor charge of interfering with school faculty. That charge carries a maximum of 18 months in jail.
Kusick is due in a Jefferson County court in December for a hearing on the misdemeanor charge.
A grand jury will hear the federal case and must hand up an indictment for the case to trial.
