A man who ran for Congress last year in East Tennessee has pleaded guilty to plotting an attack on a small Muslim enclave in New York.

The plea agreement entered last month says federal agents began investigating Robert Doggart of Signal Mountain following a Facebook posting in which he claimed a community outside of Hancock, New York, was planning a terrorist attack and "must be utterly destroyed."

This area is known as "Islamberg," a self-named community consisting primarily of Muslims.

Doggart faces up to five years in prison and a $250,000 fine. His attorney told The Associated Press on Tuesday that a judge is still reviewing the plea agreement.

Doggart ran as an independent in last year's District 4 congressional race and finished with just 6 percent of the vote.
