Nicholas Savino, 42, was indicted by a grand jury last year after he referred to the president as the "Anti-Christ" and threatened his life in a message published in August 2013, according to a statement issued by the U.S. attorney's office in Pennsylvania.
“President Obama the Anti-Christ. As a result of breaking the constitution you will stand down or be shot dead," Savino wrote.
The president was scheduled to make several appearances in Pennsylvania the same month Savino posted the threat. One of the appearances was at Lackawanna College, less than 10 miles from Clarks Summit, where Savino lived.
Police found about 11,000 rounds of ammunition and three firearms after searching Savino's vehicle. Savino pleaded guilty to the threat charge, according to the statement, and will have to forfeit his weapons and ammunition as conditions of the plea agreement.
He will also be subject to two years of supervised release and must pay a $3,000 fine, the statement said.
