This apology is incomplete. Beck involved Obama's children in another attack on the president earlier this week, comments Beck did not address in his apology today.
Further, Beck limited his apology to just "my own rule about leaving kids out of political debates." But he has repeatedly stated that entire families are off-limits -- and he has dragged President Obama's family into "political debates" several times over the past year. In a sexist attack on the president's wife just last week, Beck referred to an image on the Drudge Report of Michelle Obama at a White House state dinner for the Mexican president and his wife, stating:
I don't think I've ever seen the first lady with her -- excuse the expression -- but with her breasts all smooshed up.
Beck has also repeatedly brought up Obama's parents on his Fox News and radio shows -- specifically in the context of discussing Obama's politics -- and more than a year ago, he made fun of President Obama's aunt.
Glenn Beck's apology is incomplete until he apologizes for all the other instances in which he dragged the president's family into his political attacks.
