If several Donald Trump’s Republican rivals have any thoughts about the GOP frontrunner’s decision to skip Thursday’s debate in Iowa to hold a fundraiser for his charity foundation, they aren’t speaking up about it.

Trump claims his event, which is being held just down the road from the Fox News-sponsored debate, will seek to raise money for veterans, though the website set up for the occasion actually directs donations to the Donald J. Trump Foundation. The foundation, a non-profit that has given just more than $10,000 to veterans’ groups per year between 2009 and 2013. Trump’s donation form promises that all the money collected in association with Thursday night’s event will go to help veterans, but the specifics end there.
