A 27-year-old Illinois man was arrested this week on federal charges of making threats against President Donald Trump, the FBI announced on Tuesday.
Preliminary and detention hearings are scheduled for Monday at 2 p.m. at the federal courthouse in Peoria.
The investigation was led by the FBI's Springfield Field Office with help from the United States Secret Service, the El Paso Police Department, the Woodford County Sheriff's Office, and the Illinois State University Police Department.
That Oct. 17 arrest stemmed from allegations that he disrupted two informational tabling events hosted by a registered student organization over a week earlier.
Lopez was relieved of his teaching duties pending further investigation following that incident, according to Illinois State University Director of Media Relations Chris Coplan, as reported by the student newspaper The Vidette.
The university released a statement Oct. 18 addressing the issue and noting its commitment to diverse perspectives and civil discourse.
"We expect everyone to listen and respond to opposing views with civility," the statement read.
Police Chief Aaron Woodruff said the department remains "committed to protecting the First Amendment rights as well as safety of everyone in our campus community.”
The FBI reminded the public that charges in a complaint are merely accusations and a defendant is presumed innocent unless proven guilty in a court of law.
Lopez's arrest comes amid a series of threats against high-ranking federal officials this year.
Prosecutors said Monper's posts included a February comment that said, "We just need to start killing people, Trump, Elon, all the heads of agencies Trump appointed, and anyone who stands in the way.”
