Where did waltz get $$$

 Where did waltz get money to get a mansion and now spending 12.8 million to remodel it... Alot of money he is spending for being a school teacher before governor of Minnesota. And also he let Minneapolis burn and did nothing... Thinking corruption and he's getting paid off....  Waltz has FAILED MINNESOTA  AND WILL KEEP FAILING TO PAD HIS POCKETS.... CORRUPTION IN MINNESOTA
