Paul Nehlen is challenging Rep. Paul Ryan to represent the 1st Congressional District of Wisconsin.

The Washington Times first broke the story earlier this week, but the challenger hadn’t yet released his name. Nehlen officially came forward Wednesday.

“Paul Ryan’s embrace of big government spending, his continued support of illegal immigration and imported workers, and his championing of the job-killing trade deal known as the Trans-Pacific Partnership betrays me, this district, and this nation,” he is quoted as saying.

On his Facebook page, Nehlen says that Ryan’s continued backing of President Barack Obama‘s immigration policy puts an un-named American city on track to become the next Brussels. That city suffered two terrorist attacks last week that killed dozens and injured hundreds.

“By essentially aiding and abetting President Obama in an array of dangerous immigration policies Ryan has potentially funded the next Brussels catastrophe, right here at home,” his post reads. “We have a significant problem here and need to behave accordingly. Ryan simply isn’t going to make that happen.”

According to his LinkedIn profile, Nehlen is the senior vice-president of operations at Neptune Benson in Lake Geneva. The company is a water filtration and UV disinfection systems manufacturer, and Nehlen holds several patents for industry technologies.

He lives in Delavan, and the WT story notes that TEA Party activists have been looking for a viable candidate – albeit one with a steep uphill battle – to challenge Ryan after the Speaker voted for a $2 trillion spending package last year.

The partisan primary election is August 9, and the general election is Nov. 8.
