MSNBC’s latest public apology shows the network has a problem that is “spiraling out of control,” TheBlaze’s S.E. Cupp said Thursday.

The network prompted outrage Wednesday after it sent a tweet claiming that “the rightwing” would supposedly “hate” a Cheerios commercial because it featured a biracial family. It eventually responded to online pushback by deleting the offending tweet and issuing a retraction.

Cupp is a former co-host of MSNBC’s “The Cycle,” a show on which race “came up a lot.”

“I always welcomed that idea where someone, some less thoughtful pundit, would introduce that idea that half the country is racist because they’re Republican, because I thought, ‘This is great. If liberalism exposes tolerance, I’m glad we are showing and exposing that lack of tolerance for what it is,” she said Thursday on TheBlaze TV’s “Real News.” “It’s all they can see.”

Cupp added that it was also fun “shooting down” these ideas when they were brought up by her former MSNBC colleagues.

“But when it comes in an official capacity from the network,” she said, referring to the Cheerios tweet, “I think that’s deeply disappointing. Deeply, deeply disappointing.”

MSNBC President Phil Griffin issued a formal apology after Republican National Committee Chairman Reince Priebus announced that he had banned all RNC staff from appearing on the network as a result of the tweet.

This latest incident came just weeks after MSNBC host Melissa Harris-Perry was forced to apologize for leading a panel that mocked Kieran Romney, former Gov. Mitt Romney’s adopted black grandson.

“That says to me that a culture has created an acceptance, a willingness, a complicity in allowing that line of thinking to seep out into the mainstream officially,” Cupp continued. “I’m sure Phil Griffin believes that’s a real problem. … I’m sure they realize that’s a problem.”

She said the recent controversies surrounding Harris-Perry, ex-host Martin Bashir’s suggestion that someone should defecate in former Alaska Gov. Sarah Palin’s mouth and ex-host Alex Baldwin shouting anti-gay slurs signals the network has a problem that is “spiraling out of control.”
