his excuse was that he was trying to find his right charity to donate to
Yeah, so bonkers. Naming a specific charity for 10 years and then to claim that all that time was spent to find the right charity is such an obviously dumb lie. Before the golf tournament thing came out, he could just have claimed "Oops, I could have sworn I made a recurring donation and I just didn't look at the numbers all that time. Seems I made an error, my bad, sorry." and nobody could have disproven it having been a dumb human error.
