(CNN) – As of Saturday, Arizona Democratic Rep. Gabrielle Giffords' name appeared on a website titled "take back the 20" as part of a list originally issued by Sarah Palin of vulnerable House Democrats. A map on the site showed crosshairs over the contested Democratic districts.
Palin first posted the list in March 2010, naming 20 House members who voted for health care reform and represented districts that Republican Sen. John McCain of Arizona won in the 2008 presidential election.
At the time, Giffords responded to the map by saying on MSNBC that her long-serving colleagues had "never seen anything like it."
"The thing is, the way that she has it depicted has the crosshairs of a gun sight over our district," Giffords said in March. "When people do that, they've got to realize there's consequences to that action."
After Giffords was shot in Tuscon, Arizona, Saturday, Palin responded on her Facebook page:
"My sincere condolences are offered to the family of Rep. Gabrielle Giffords and the other victims of today's tragic shootings in Arizona. On behalf of Todd and my family, we all pray for the victims and their families, and for peace and justice."
At a press conference Saturday, Pima County Sheriff Clarence Dupnik criticized people who are making a living off "inflaming the American public."
"When you look at unbalanced people, how they respond to the vitriol that comes out of certain mouths about tearing down the government, the anger, the hatred, the bigotry that goes on in this country is getting to be outrageous," Dupnik said. "Unfortunately, Arizona has become sort of the capital. We have become the Mecca for prejudice and bigotry."
And Saturday's tragedy was not the first time the Arizona Democrat was targeted. The day after she voted in favor of health care reform, a glass panel at her Tucson office was shattered.
Giffords won a close race against Republican Jesse Kelly in November. Kelly was a Tea Party favorite who ultimately received 47 percent of the vote to Giffords' 49 percent. The Republican-leaning 8th district went for George W. Bush in 2000 and 2004.
Tea Party Express Chairwoman Amy Kremer responded to the events Saturday by saying the group is "shocked and saddened" by the "terrible tragedy."
"These heinous crimes have no place in America, and they are especially grievous when committed against our elected officials. Spirited debate is desirable in our country, but it only should be the clash of ideas," Kremer said in a statement. "An attack on anyone for political purposes, if that was a factor in this shooting, is an attack on the democratic process. We join with everyone in vociferously condemning it."
