West Virginia State Police detained a 42-year-old man after a search of his vehicle revealed explosive powder and a firearm.
Interstate 68 was shut down for around four hours after someone threatened to kill President Trump and to blow up the Pentagon.
Secret Service and the FBI are coordinating with state police on the investigation.
Law enforcement has yet to release further details.
UPDATE: State Police Captain Shallon Oglesby said that the shutdown on I-68 came after a routine traffic stop at about 10:30 a.m. Wednesday for speeding along the eastbound lanes. https://t.co/ZdELcNIvuE
