Former president Donald Trump was acquitted Saturday of inciting the Jan. 6 attack on the Capitol, becoming the first president in U.S. history to face a second impeachment trial — and surviving it in part because of his continuing hold on the Republican Party despite his electoral defeat in November.

That grip appeared to loosen slightly during the vote Saturday afternoon, when seven Republicans crossed party lines to vote for conviction — a sign of the rift the Capitol siege has caused within GOP ranks and the desire by some in the party to move on from Trump. Still, the 57-to-43 vote, in which all Democrats and two independents voted against the president, fell far short of the two-thirds required to convict.
