In a statement shortly after the acquittal, Trump called the trial “yet another phase of the greatest witch hunt in the history of our nation”.
“Our historic, patriotic and beautiful movement to Make America Great Again has only just begun,” he said.
“In the months ahead, I have much to share with you, and I look forward to continuing our incredible journey together to achieve American greatness for all of our people,” he added.
Trump left office on January 20, so impeachment could not be used to remove him from power.
But Democrats had hoped to secure a conviction to hold the 74-year-old responsible for the Capitol siege and set the stage for a vote to bar him from serving in public office again.
Though Trump was acquitted of the sole charge of incitement of insurrection, seven Republicans joined all Democrats to convict the former president. The figure marked the largest number of Senators to ever vote to find a president of their own party guilty of an impeachment count of high crimes and misdemeanours.
They were Richard Burr of North Carolina, Bill Cassidy of Louisiana, Susan Collins of Maine, Lisa Murkowski of Alaska, Mitt Romney of Utah, Ben Sasse of Nebraska and Patrick Toomey of Pennsylvania.
Trump is only the third president ever to be impeached by the House of Representatives – a step akin to a criminal indictment – as well as the first to be impeached twice and the first to face an impeachment trial after leaving office.
After Saturday’s verdict, Senate Republican Leader Mitch McConnell, who voted “not guilty,” in the trial, offered scathing remarks about Trump.
“There is no question that President Trump is practically and morally responsible for provoking the events of the day,” he said. “The people who stormed this building believed they were acting on the wishes and instructions of their president.”
McConnell suggested that Trump could still face criminal prosecution for his acts, however.
“President Trump is still liable for everything he did while he was in office as an ordinary citizen,” McConnell said. “He didn’t get away with anything. Yet.”
The minority leader was not the only Republican to castigate Trump for his behaviour after voting for acquittal.
“The question I must answer is not whether President Trump said and did things that were reckless and encouraged the mob. I believe that happened,” Senator Rob Portman in a statement.
“My decision was based on my reading of the Constitution,” the Ohio Republican added. “I believe the Framers understood that convicting a former president and disqualifying him or her from running again pulls people further apart.”
Senator Chuck Grassley, the Senate’s most senior Republican, described Trump’s language in a fiery speech to supporters just before the Capitol assault as “extreme, aggressive and irresponsible”. But he said the Senate had no jurisdiction to hold a trial, agreed with Trump’s legal team that the former president deserved more “due process” and said the prosecution had not made their case.
Claire Finkelstein, professor of law at the University of Pennsylvania, said most of the Republicans who had voted to convict Trump were politicians who were not planning to run for office again.
“Those who are steadfast in insisting on the innocence of Donald Trump here are primarily those with political ambitions. They have fused themselves to Donald Trump. And he will control the agenda. And it gives him a wonderful platform from which to run again in 2024,” she said.
