According to White House Press Secretary Sarah Huckabee Sanders, Donald Trump is pledging $1 million dollars for Hurricane Harvey relief efforts—exactly $4 million dollars less than when he offered Barack Obama $5 million for his birth certificate in 2012. Because priorities: 

Sure, $1 million is a lot of money, but Donald Trump is also worth $10 billion dollars (allegedly). Folks on Twitter were quick to note that it makes his $1 million donation .01% of his assets. “Median net assets for Americans = $44,900. So it's like donating $4.49.” That is, if that money even comes from him and not the Trump Foundation instead. Say, did President Obama ever get that check?
