evidence: President Donald Trump had just returned to the White House from his rally at the Ellipse on Jan. 6 when he retired to his private dining room just off the Oval Office, flipped on the massive flat-screen television and took in the show. At the other end of Pennsylvania Avenue, thousands of his supporters were wearing his red caps, waving his blue flags and chanting his name. [...] Trump began speaking at the Ellipse at 11:57 a.m. Midway through his speech, the president publicly pressured his vice president, telling his supporters: "If Mike Pence does the right thing, we win the election. … Mike Pence is going to have to come through for us, and if he doesn’t, that will be a sad, sad day for our country." [...] Back at the Ellipse, Trump was finishing his speech, and the leader’s edict rang through the city like a call to arms.
