I love it when liberals get all triggered over financial matters. It's almost as if when they can't get others to pay their bills, they cry like little children, or parasites who want to live off the government!
Trump shouldn't have to pay for his political campaigns any more than the Big Guy should have to dip into his Chinese bribe money to pay for his.
Legal fees... well, if he wasn't constantly hounded by leftards with no proof of any wrongdoing, then I might say yes, Trump should pay. But since the left's philosophy is not to investigate a crime and look for the person who committed it, but instead they look at Trump and want so badly to believe he has committed a crime, and investigate him for that, then I'll go with no, Trump shouldn't have to pay his own legal fees.
Trump took no salary as president; he donated it all to charity. Is Biden taking the salary and keeping it for himself? Of course he is. That should tell you plenty about the difference between Biden and Trump when it comes to loving our country.
