Glenn Beck already apologized for that slanderous lie.
Thanks for the correction.
Here it is: Donald, then a Democrat, crossed over and went with McCain after Obama named Biden his running mate. He had been backing Hillary in the primaries, and declined to speculate as to whom he would support if Obama had named her to his ticket.
He turned into an Obama cheerleader after Obama was elected.
BTW it’s not “slander” when people accept corrections. But, you probably know that and are following your mentor’s example of how to make friends and influence people.
