Supreme Court Chief Justice John Roberts is apparently looking to sit out former President Donald Trump’s second impeachment trial — and not without good reason.

Trump’s trial, in which the Senate for the first time will weigh the alleged crimes of an ex-president, presents a tangle of constitutional difficulties for Roberts, legal scholars told the Washington Examiner. That could be good news for the chief justice, who faced harsh scrutiny during Trump’s first trial and wants no part in the second go-around, according to multiple reports.
