Court House - Can anyone explain to me how our "great president????" can own the most expensive house in Delaware along with at least 2 other houses near water front on a tax payer produced salary?? My bet is there is clear criminal activity that has provided Biden Family with huge junks of income AND is why he has shut down American oil drilling and begging for oil from countries that do not like us except for our money and would love to see this country fail...Keep voting Democrat and enjoy the expensive life in U.S.
