A 17-year-old McKinney boy was arrested Oct. 5 in connection with an alleged plot to assassinate U.S. Rep. Keith Self, according to news reports and a statement from Gov. Greg Abbott’s office.

WFAA first reported that the FBI arrested and charged the teenager after he obtained a firearm, citing unnamed federal law enforcement sources. Those sources said investigators also suspected him of preparing a separate attack in North Texas on behalf of ISIS.

The teenager’s identity and specific charges were not disclosed in the reports. Abbott’s office said in an Oct. 22 announcement that he remained in federal custody.

Self’s campaign told NBC 5 that U.S. Capitol Police notified the congressman’s team of the arrest Oct. 6. The campaign said the alleged target was an Oct. 17 chili cook-off benefiting veterans, where Self was expected alongside former Dallas Cowboys players and other guests.

Self attended the fundraiser and said his team increased its vigilance after learning of the threat.

“I judged 19 different chilies and three different pots of beans,” he told NBC 5.

The Republican represents Texas’ 3rd Congressional District, which includes Murphy and parts of Wylie and Sachse. He is seeking a third term against Democratic nominee Evan Hunt in the Nov. 3 election.

In an Oct. 21 post on X, Self thanked law enforcement and said his family was safe. He also cited his 25 years of military service and pledged to continue his work.

“This only strengthens my resolve. I will not back down,” he wrote.

Self told Wylie News that Capitol Police contacted him twice about the arrest. Asked whether the threat would slow his campaign, he answered, “Absolutely not!”

WFAA reported that federal agents had been monitoring the teenager before his arrest and that sources described him as recently radicalized. NBC 5 said it had requested information from the FBI’s Dallas office but had not received a response.

Hunt also condemned the alleged plot. In a statement shared with WFAA, he said political disagreements never justify threats and thanked law enforcement for protecting public officials.

“We must settle our differences through debate and at the ballot box,” Hunt said.
