He’s obviously not trustworthy but as a political fundraiser I’ll just say that

1. for donors like him it’s very normal to play both sides because you believe it will stop you from getting regulated

2. Republicans are always much more likely to funnel their money through IEs than to raise into disclosable accounts because their donors are less willing to be publicly associated, so this is how it would likely look mechanically if he was

3. It was widely believed in DC circles that he was playing both sides prior to him making this claim, Teddy Schleifer has covered this extensively if you want a source.

I’m ultimately not remotely worried about losing him as a donor. The most effective Dem groups all have limits and most of the IE groups are leaches trying to grift money of billionaires that don’t do anything but charge themselves consulting fees. Probably 5-10% of this was actually spent in a way that helped win elections.
