No, he doesn’t need to grovel any more. I’m tired of groveling everytime some milquetoast Leftist tells us we have to repent. His apology of “Sure, I’m willing....” is easily enough...there’s no need for us to be political simps about it.
Its not groveling, it’s an opportunity for the President to shine. They only asked hoping he would decline so they could create a media firestorm.
