One of the architects of failed gun control legislation says he's bringing it back.

Sen. Joe Manchin on Sunday said he would re-introduce a measure that would require criminal and mental health background checks for gun buyers at shows and online. The Democrat says that if lawmakers read the bill, they will support it.

Manchin sponsored a previous version of the measure with Republican Sen. Pat Toomey of Pennsylvania. It failed.

Manchin says there was confusion over what was in the bill.

Congress took up gun control legislation in the wake of the school shooting that killed 20 children and six adults in Connecticut last year. But it was blocked by supporters of the powerful pro-gun lobby, the National Rifle Association.

Manchin appeared on "Fox News Sunday."
