After a tumultuous opening month in the White House, President Donald Trump is heading to a friendlier, familiar and potentially rejuvenating place: the campaign trail.

Beset by vicious fights over his Cabinet, legal setbacks over his immigration orders, the resignation of his national security adviser and an investigation into possible links between his campaign and Russian intelligence, Trump is turning to the winning formula that vaulted him into the White House: Big, adoring crowds and fiery, angry speeches.

He has replaced Hillary Clinton, his former Democratic presidential rival, with a new foil: Newspapers and TV news outlets that have reported unflattering revelations of dysfunction or other problems in the White House. He has described them as "lying," "corrupt," "failing" and, late on Friday, as "the enemy of the American people."
