One gun rights activist in Texas said he planned to “open carry my rifle” at President Barack Obama’s SXSW keynote on Friday, according to a report from the New York Daily News.

Open Carry Texas founder C.J. Grisham wrote the event “may get interesting” in a closed Facebook groups with 28,000 members on Wednesday, according to the newspaper.

Grisham said the “interesting” comment was referring to getting around busy downtown Austin during the increasingly popular conference.

Secret Service spokesman Robert Hoback told the Daily News that the agency was “aware of this posting and is conducting the appropriate follow up.”

But Grisham said he hasn’t heard from law enforcement.

“I don’t understand what people get out of that,” he told the Daily News. “I know that those guys are smarter than the people who are making a big deal out of this.”

The Secret Service can prohibit guns from presidential events in open-carry states like Texas, per federal law.

Hoback also said armed individuals would not be allowed into the interview between Texas Tribune editor-in-chief and CEO Evan Smith and the President.
