Trump’s defense team accused the House managers of subverting democracy and cherry-picking evidence.

After three days of arguments by the House managers prosecuting President Trump for high crimes and misdemeanors, the president’s lawyers presented the senators a radically different view of the facts and the Constitution, seeking to turn the Democrats’ charges back on them while denouncing the whole process as illegitimate.

“They’re asking you to tear up all of the ballots all across the country on your own initiative, take that decision away from the American people,” the White House counsel, Pat A. Cipollone, said of the House managers. “They’re here,” he added moments later, “to perpetrate the most massive interference in an election in American history, and we can’t allow that to happen.”

Another of Mr. Trump’s lawyers, Michael Purpura, repeatedly pointed to clips of testimony from the House’s impeachment inquiry that he said undermined the argument that Mr. Trump had engaged in an illicit quid pro quo by holding military aid from Ukraine while pressuring the country to announce investigations into his political rivals.

“We know there was no quid pro quo on the call, we know that from the transcript,” Mr. Purpura said. “There couldn’t possibly have been a quid pro quo because the Ukrainians didn’t know the security assistance was on hold” until a Politico article reported that, he said.
