A Tennessee lawmaker who posted a joke about the pressure cooker bombs used to murder three people last week in Boston now says that people need to "lighten up."

In a post to his personal blog on Monday, state Sen. Stacey Campfield (R) displayed a photo of an "Assault Pressure Cooker" with the title "Here comes Feinstein again."

The photo described the pressure cooker as having a "folding stock," being the "evil" color black and having a "large-capacity, can cook for hours without reloading."

The joke is a reference to Sen. Diane Feinstein's (D-CA) effort to ban military-style assault weapons, which gun proponents argue uses cosmetic features to decide which rifles will be outlawed.

WVLT asked Campfield if had been appropriate to joke about crock pot bombs less than a week after terrorists used the improvised explosive devices in Boston.

"People need to lighten up," Campfield told the station. "I say it's insensitive that people go after guns and Second Amendment rights after the Sandy Hook shooting."

"I Just [sic] got a call from the media saying they had gotten a few calls (about a blog post I did) saying it was inappropriate after the Boston bombing," the state senator wrote in a follow-up post. "If my post was inappropriate talking about 'crock pot control' then where is the outrage from the left when they push for gun control after the Sandy Hook shooting? Im [sic] sorry if I exposed your double standard.... Well, not really."

On Tuesday, Campfield added, "How come no one ever says its liberals who are bitterly clinging to their gun control and secular humanism?"

Earlier this month, the Tennessee lawmaker dropped a bill linking a student's academic performance to their family's welfare benefits after an 8-year-old girl shamed him by following him around the state Capitol. He also recently threatened to cut funds for the University of Tennessee after he learned that the school was conducting a "Sex Week" to promote sex educcation.

In February, he told TMZ that he had proposed a law that prevented students from being taught about homosexuality because the "homosexual community gets AIDS at a 50 times higher rate than the heterosexual community."

When asked why students shouldn't be taught how to protect themselves from HIV, Campfield compared homosexuality to "shooting heroin."

“We need to show them the best ways to shoot up. No, we don’t," he said. "Why do we have to hypersexualize little children? Why can’t we just let little kids be little kids for a while?”
