Are you serious? You don’t know how to find wrongdoing without looking for it? Wow! It goes like this...a crime is committed, then law enforcement investigates to identify the perpetrator(s) and gather evidence. They don’t or are not supposed to just willy nilly decide to investigate in hopes of finding a crime. As for the 4th Amendment, President Trump was a private citizen at the time and his family and business associates are still private citizens. Do you seriously want Congress critters of any stripe to arrogate to themselves the power to investigate their political opponents for no legal reason?
greymattr’s job it to put a reasonable face on the left while appearing to be conservative.
