Rick Perry's presidential campaign is out of money. The official statement from his camp put it differently, saying that "tough decisions have to be made in respect to both monetary and time-related resources."

In other words, his people are working without pay, according to Fox News.

"Governor Perry remains committed to competing in the early states and will continue to have a strong presence in Iowa, New Hampshire and South Carolina," Perry campaign spokesperson Lucy Nashed said in a statement. These three states hold their primary elections first.

Right now, Perry's South Carolina staff is working on a volunteer basis. "We'll do it whether there's pay or no pay," state director Katon Dawson said, Fox News reported.

Perry was among the seven candidates who could not participate in last Thursday's main Republican debate on Fox News. He did not poll high enough to be included in the prime time slot, according to The Huffington Post. Perry also ran for president in 2012. The Republican nomination eventually went to Mitt Romney.

Perry's financial problems could end his campaign well before the Iowa caucuses are held on Feb. 1, 2016. That's almost six months away.

So far, Perry has raised just more than $1 million for his campaign, according to The New York Times.
