Background reading:

• President Trump has become the first president to be impeached twice, after the House approved a single chargea single charge of inciting the mob that stormed the Capitol. He faces a Senate trial that could disqualify him from future office.
• Senator Mitch McConnell is said to have privately backed the impeachment of Mr. Trump.
• The second impeachment — in a Capitol ringed by troops — seemed like the almost inevitable culmination of four years that left the nation fractured, angry and losing its sense of self.
