Mark Kelly, the husband of former Rep. Gabrielle Giffords, knocked Arizona Sen. Jeff Flake for his opposition to the Senate gun control bill -- saying he's one of many lawmakers "looking for a reason to get to no."

"It appears to me that maybe he hasn't read the bill because his concerns are addressed in the legislation," Kelly said at a Christian Science Monitor breakfast.

Giffords was severely wounded in the 2011 Tucson mass shooting. She and her husband have since launched a campaign urging lawmakers to approve expanded background checks and other provisions.

Flake, though, said on his Facebook page that the current proposal "goes too far."

Kelly has a meeting with Flake later Tuesday. "When I explain to him in person, I think we can get him to come around," Kelly said.

Asked what would happen if Flake ends up not supporting this bill, Kelly said his organization would seek to replace him in the Senate. "Friendship is one thing, saving people's lives is another," he said.
