After Elisabeth Hasselbeck suggested the #BlackLivesMatter movement should be labeled a hate group, Rosie O’Donnell declared her former View co-host was being ignorant.

On Monday's Fox and Friends, Hasselback pondered, "Why has the #BlackLivesMatter movement not been classified yet as a hate group? I mean, how much more has to go in this direction before someone actually labels it as such?”

The reality contestant-turned-talking head was discussing the execution-style murder of Houston deputy Darren Goforth on Friday by an African-American suspect.

O’Donnell tweeted Hasselbeck’s question and added, "Some are slow to wake."

There is currently no evidence that Goforth’s suspected killer, Shannon J. Miles, was a supporter of #BlackLivesMatter. Also, the movement is not a organized group with a single mission statement, offices or agenda. It would be impractical (and irresponsible) to label a hashtag sentiment a "hate group.”

The former colleagues clashed repeatedly while sharing the panel on The View. A 2007 feud got so heavy that it reportedly led to O’Donnell leaving the show before her contract was up.
