Republicans have no unified argument in the impeachment inquiry of
Donald Trump , in large part because they can't agree on how best to defend the president — or for some, if they should.
Or it would take a measure of GOP independence from Trump to suggest there may be a need to investigate.
Utah Sen. Mitt Romney says the president's actions toward
Ukraine are "troubling." Other
Republicans say the behavior may raise concerns, but it's not impeachable.
