Trump is not a Christian

After watching Trump and JD Vance belittle and bully the Ukrainian President today. I ask you. Is this how Christians act? Do you give aid to one in need and expect something in return? Do you need to be thanked for your benevolence? WWJD? Explain how any Christian can support this guy. Not to mention everything else he’s done. Felony convictions of fraud. Convictions of sexual abuse, adultery? I’m just asking from a theological perspective?
