When there is a pattern of questionable conduct and/or alleged improprieties, AND the individual is a public official much less a Senator of the US who has just been elevated to a new role, we do NOT need indictments, arrests, lawsuits, and the like.
What we need instead is a confident and open response in which the individual confronts reporters and answers questions about what actually happened, why, when, how, where, and with whom. We could ask him about the illegal alien registered sex offender working on his staff, too. Instead, the Senator takes a side elevator to an empty hallway to another elevator to slip out of the Capitol building unnoticed.
He should just step down if he knows the accusations are even "mostly" true.
