The publisher of a controversial coloring book company says that the White House emailed profanity to his company after one of President Barack Obama's friends was included on its "The True Faces of Evil – Terror" list.

Really Big Coloring Books founder Wayne Bell on Wednesday told Fox News host Gretchen Carlson that sales of his company's "Tea Party Coloring Book for Kids" and "U.S. Constitution Book Just for Kids" had taken off following coverage of a Republican investigation into the Internal Revenue Service for targeting conservative groups.

Bell pointed out that the White House had not been happy with his company last year over a coloring book about the terrorist attacks of September 11, 2001.

"We did the original 'We Shall Never Forget 9/11,'" he explained. "And then we followed it up with the year after with 'The True Faces of Evil - Terror.' And this book prompted an email from the White House email server, in which they basically said, you know, really not nice things to our company."

"Why?" Carlson wondered.

"Because we put people -- we put the evil people in here," Bell insisted.

"You had Bill Ayers, who was at one time an associate of Barack Obama," Carlson observed. "Is that why they were angry about that?"

"I think so because they basically told us 'you f---ing' -- I know, but they didn't write it out," Bell recalled. "Our graphics and our forensics people on our web team [said] the email came from We responded to the email and told them this is very inappropriate. The person signed it with their initials, and we never heard back from them."

"And so, we think they were just upset because because we did a book on terror that tells the truth about terrorism."

Bell also insisted that his company tries to serve all audiences because it created "Yes We Can" and "Occupy" coloring books.

But the Occupy Wall Street coloring book "sold better in China and France than it did in the U.S.A.," he said.
