An ominous-looking black billboard with Arabic script and the name "Donald Trump" appeared over a Michigan highway last weekend. It says: "Donald Trump, he can't read this, but he is afraid of it."

The campaign is funded by Nuisance Committee, a Super-PAC with the goal of "driving Trump nuts."

A website in the bottom corner directs people to, a campaign calling out the Republican candidate's stance on Muslims, who he has said he will bar from entering the United States or subject to "extreme vetting" if he is made President.

In a campaign stop in Wisconsin Monday (October 17) Trump said he plans to "stop the massive inflow of refugees" to the US.

The Nuisance Committee was set up by the founder of the board game Cards Against Humanity. Super-PACs are funds that can raise as much money as they want from corporate or individual donors to spend on political advocacy.

The group is "dedicated to opposing Donald Trump's presidential campaign and repudiating his backwards, un-American policies of white nationalism and fascism," according to online postings. So far it has raised $410,000.

"If Trump is so rich, how come he didn't buy this billboard?" asks another funded by the group in a campaign aimed at underscoring Trump's record on paying taxes.

"I feel like we are able to exploit the media's thirst for Trump by doing these sorts of jokes," said the Cards Against Humanity's founder Max Temkin in an interview about the advocacy fund.

Trump "arbitrages the media's unstoppable need for Trump stories by saying crazy stuff and getting millions of dollars of earned media whenever he tweets," he said. "The more we can pick these provocative issues and do them in a surprising way, the more we'll get our share of the media on the other side."
