After six months in office, Mr. Trump has crossed so many lines, discarded so many conventions, said and done so many things that other presidents would not have, that he has radically shifted the understanding of what is standard in the White House. He has moved the bar for outrage. He has a taste for provocation and relishes challenging Washington taboos. If the propriety police tut tut, he shows no sign of concern.
“His tweet is bizarre and unprecedented,” said James A. Thurber, the founder and former director of the Center for Congressional and Presidential Studies at American University in Washington. And yet, “he has made so many outlandish statements, Americans seem to be immune to this latest call for investigating Hillary.”
On the day Mr. Trump called for a criminal investigation of his rival, he asserted on Saturday that he had the “complete power to pardon” his friends, relatives and possibly himself to short-circuit a special counsel’s investigation into any possible collusion between his team and Russia during last year’s campaign. While he said he did not need to use his pardon power at this point, presidents rarely if ever publicly broach the idea of pardons amid an investigation.
Just hours later, Mr. Trump urged uniformed sailors aboard the aircraft carrier Gerald R. Ford to call their members of Congress to lobby for his military spending plan and his proposed repeal of Mr. Obama’s health care program. Traditionally, the commander in chief does not tell the troops who serve under him to involve themselves in politics or policy battles on his behalf.
By now, it takes more to shock. After all, this is a president who refused to release his tax returns or divest from his private businesses, who put his son-in-law and daughter on the White House staff, who accused his predecessor of illegally tapping his phones without proof, who fired the F.B.I. director leading an investigation into the president’s associates and who has now undercut his “beleaguered” attorney general in public. When he talked politics, jabbed the news media and told stories about Manhattan cocktail parties before tens of thousands of children at the nonpartisan National Scout Jamboree here in West Virginia on Monday, it was hardly surprising.
