The question is no longer whether there are grounds to impeach Donald Trump. It is when enough Republicans will put their loyalty to America ahead of their loyalty to their party.
Trump’s statements last week about his firing of former FBI director James Comey provide ample evidence that Trump engaged in an obstruction of justice – a major charge in impeachment proceedings brought against Richard M. Nixon and Bill Clinton.
It’s worth recalling that the illegality underlying Nixon’s impeachment was a burglary at the Watergate complex, while the illegality underlying Clinton’s was lying to a grand jury about sex with an intern in the White House.
Trump’s obstruction is potentially far more serious. It involves an investigation about whether Trump or his aides colluded with Russia in rigging a presidential election – the most direct assault on American democracy in history.
