CNN Host Tears Into 'Mean, Smug' MSNBC for Mocking Romney's Black Grandson

It was a battle of the networks yesterday as CNN's Don Lemon ripped into "smug" MSNBC for making jokes about Mitt Romney's adopted grandson Kieran, who is black.

It started on Melissa Harris-Perry's show, where she put up this Romney tweet and opened it up for her guests to "caption."

Actress Pia Glenn began singing, "One of these things is not like the others." Comedian Dean Obeidallah mocked the family picture for "really [summing] up the diversity of the Republican Party."

Lemon's take later on CNN? "It's a bunch of people on the left who all agree with each other, and there's no diversity of opinion," he said of MSNBC. "And they're saying mean, smug things about people who may disagree with them."

“If someone on Fox [said], ‘one of these things is not like the other,’ to a black baby in a white family, what do you think would happen?” Lemon asked, pointing out the double standard.

Harris-Perry tweeted an apology today: "I am sorry. Without reservation or qualification. I apologize to the Romney family. I work by guiding principle that those who offend do not have the right to tell those they hurt that they [are] wrong for hurting. Therefore, while I meant no offense, I want to immediately apologize to the Romney family for hurting them. As black child born into large white Mormon family I feel familiarity w/ Romney family pic & never meant to suggest otherwise. I apologize to all families built on loving transracial adoptions who feel I degraded their lives or choices."
