He mentioned he knew the number hadn't been donated as of 2021, so it's entirely possible he wasn't directly involved in the charity other than running donation drives. Yes he was an officer that whole time, but it's very reasonable to say that a sibling was doing most of the charity work.

This doesn't absolve him of responsibility (he's an officer, so he should be aware), and he still didn't donate it for two years. But it's entirely possible he didn't know it hadn't been donated for 7-8 years, and after that point he just followed the same script he'd been using. Again, it doesn't absolve him, but it does provide some important context.

Then again, this assumes what he said was true. I don't have any reason to doubt it though, because he basically admitted to multiple allegations in the same call.
