(CNN) – Amid backlash for tweeting out an article with inflammatory language, Illinois Gov. Pat Quinn's campaign said Thursday it didn't thoroughly read the story before blasting it out to its Twitter followers.
A Twitter account for the Democratic governor's re-election campaign, @QuinnForIL, tweeted out an article last week that compared black voters supporting Quinn's Republican challenger, Bruce Rauner, to Jewish people collaborating with the Nazis during World War II against their own people in hopes of being spared the same fate.
Neil Steinberg wrote the article published by the Chicago Sun Times last Thursday. The Washington Free Beacon was first to report this story.
"Let me be clear: As a general rule, individuals will sell out the interests of their groups in return for personal benefit. It isn’t just a black thing. Jews collaborated with the Nazis during World War II, helping them to round up their own people in the hopes they’d be the last to go," Steinberg wrote.
In the tweets, which were deleted from the account but saved and posted by the website Politwoops, Quinn's re-election campaign quotes a line from the bottom of Steinberg's piece with a link to the article. Politwoops is part of the Sunlight Foundation, a nonprofit that aims for more transparency in government. The Washington Free Beacon was the first to report the story.
“If Rauner is willing to throw his own money away like this, what’s he going to do when he gets his hands on ours?” the tweet read.
In another tweet that has since been deleted, Quinn's campaign account retweets one of Steinberg's tweets promoting his article.
Republicans pounced on the tweets, which Quinn’s re-election team deleted the day after the uproar.
“It’s beyond unbecoming of a Governor to insinuate that any black person who disagrees with him is a race traitor. The only traitor here is Quinn, who, after winning support from black voters in 2010, has failed to create real job opportunities for those who need it most and continues to block children from access to quality schools," Orlando Watson, the communications director for black media for the Republican National Committee, said in a statement Wednesday.
"There’s a reason why black voters in Illinois are dropping Quinn and supporting Rauner: It’s Governor Quinn’s abysmal record in the black community.”
Quinn's campaign responded Thursday, saying it didn’t read the story carefully enough before sending it out.
"We retweeted a local publication's news story on Twitter last week before thoroughly reading it and didn't realize there was an inaccurate and offensive sentence in the story. When it was brought to our attention, we immediately deleted the tweet," Quinn spokeswoman Izabela Miltko said.
Quinn is considered one of the more vulnerable governors up for re-election this year. In seeking his second full term after taking over for former Gov. Rod Blagojevich in 2010, Quinn will faces Rauner, a wealthy businessman who far outspent his primary opponents and continues to spend much of his own money in the general election.
Calls of racism have come from both sides recently in the political world. Democrats and Republicans have expressed outrage over rancher and anti-government activist Cliven Bundy's suggestion that African Americans would be better off as slaves than under the control of an oppressive federal government.
