Bush accuses Trump of "currently indulging in revisionist history", saying of Trump's suggestion the Access Hollywood recording is fake, "This has hit a raw nerve in me".
He says he would like to set Trump, who is engaging in "revisionist history" by trying to convince people that he did not in fact utter the phrase, straight. "'Grab 'em by the pussy.' Of course he said it".
I can only imagine how it has reopened the wounds of the women who came forward with their stories about him, and did not receive enough attention.
But that was before the watershed moment of reckoning America is now experiencing after scores of sexual assault and harassment claims have felled entertainment, political, media and business leaders who abused their positions of power.
Bush, who was sacked from NBC's Today shortly after the tape emerged, has tried to restore his reputation in recent months by publicly atoning for his role in the scandal.
In his commentary Sunday, Bush said he believed some of the women who have publicly accused Trump of forcibly kissing and groping them in different encounters over the past two and a half decades, saying their accounts line up with Trump's comments on the bus. "Nobody has more respect for women than I do", he said previous year after the Access Hollywood tape was released.
Was I acting out of self-interest?
One alleged victim, Kristin Anderson, said that Trump reached under her skirt and "touched her vagina through her underwear" while they were at a NY nightclub in the 1990s.
So while Bush doesn't cop to enabling Trump's sexual transgressions, he does confess that he and the others present that day were guilty of "sacrificing a bit our ourselves" to climb the corporate ladder.
He continues: 'To these women: I will never know the fear you felt or the frustration of being summarily dismissed and called a liar, but I do know a lot about the anguish of being inexorably linked to Donald Trump.
"I know that I don't need the accouterments of fame to know God and be happy", he writes.
