(CNN) The Republican nominee for a US House seat in Illinois has said the September 11 terrorist attacks were an inside job and that singer Beyonce Knowles has ties to the Illuminati.

Bill Fawell is running against incumbent Democratic Rep. Cheri Bustos in Illinois' 17th District, where she won by 20 points in 2016 even though the district also voted narrowly for Donald Trump. Fawell won his uncontested primary in March. He has not reported any fundraising to the Federal Election Commission, per publicly available records.

A KFile review reveals Fawell, a real estate broker, pushed conspiracy theories in blogs and his 2012 book, "New American Revolution."

In his book, Fawell pushed a conspiracy theory that 7 World Trade Center collapsed as part of a controlled demolition and the attacks were a plot to destroy documents.

"Go to YouTube and punch in 'Building #7' It's the third building that went down with the twin towers on 9/11," Fawell wrote. "Nothing hit this building, not a thing, and it fell entirely upon its own. If it looks like a standard commercial implosion demolition, it's because that is exactly what it is."
