UPDATE: 11/22 -- The charges against Kirker were dropped earlier this month, when a handwriting analysis by the Secret Service determined that he hadn't written the offending letters.
Ryan Kirker, a 21-year-old man from McMechen, W.Va., has been charged with threatening President Barack Obama in a letter sent in April, WTRF reported Monday.
The letter, which according to the Associated Press was littered with profanity and racial slurs, reportedly concluded with the tag-line "KKK forever." It also included threats against Obama's family.
According to the Secret Service, Kircher allegedly referenced possessing a weapon and having the ability to obtain armor-piercing ammunition.
Kirker is currently being held at Northern Regional Jail on a federal complaint, WTRF reported. He will appear before a federal magistrate judge on Tuesday morning, where he will subjected to a formal handwriting analysis.
Previous records show that Kirker has been arrested on unrelated misdemeanor charges on at least two previous occasions since 2011.
