It would be negligence if he didn't. I'm sure as hell curious about what was really going on. Seems every time Joe Biden was diddling with another country on "official government bidness" folks in his family wound up making money hand over fist.Trump has every right to ask for an investigation into the Bidens. Billions of dollars in aid money has gone missing from the Ukraine while he was the point person. He should have been calling for investigations and stopped all aid until the money was found.
