Michael Hoyt worked at Wetherington Country Club in West Chester, in Boehner's home state of Ohio, and served drinks to the speaker on numerous occasions, according to a US Capitol Police affidavit published by WCPO in Cincinnati.
Hoyt was indicted on January 7 on charges he threatened to murder Boehner last October after he was fired from his bartending job, according to WCPO.
"Speaker Boehner is aware of this situation, and sincerely thanks the FBI, the Capitol Police, and local authorities in Ohio for their efforts," his spokesman Michael Steel said.
One week after he was sacked, Hoyt called 911 and told police he blamed Boehner for his woes.

He told officers he began hearing voices from his car speakers telling him that Boehner was evil, Desrosiers wrote in the document.
Hoyt also said Boehner was "responsible for Ebola," the officer said.
"Hoyt has imagined and believes John Boehner is the devil, and Hoyt believes he is Jesus Christ," Desrosiers added.
The complaint also detailed how Hoyt acknowledged to police how he could have poisoned the top Republican in Congress by putting something in his drink, but did not.
"Hoyt stated that no one checks the drinks that he poured for Boehner and it would have been very easy to slip something into his drink," Desrosiers said.
The suspect also emailed Boehner's wife, demanding a meeting with Boehner and another club member in order to resolve their dispute.
WCPO reported that Hoyt was voluntarily admitted to University of Cincinnati Medical Center for observation and evaluation.
