Opinion | The Trump Campaign Accepted Russian Help to Win in 2016. Case Closed.

Mr. Trump and his allies will parse and prevaricate forever. Ignore them. If it wasn’t already overwhelmingly clear what was going on, it is now. As the Democrats on the committee put it in an appendix to the report: “This is what collusion looks like.” Alas, the Republicans refused to join in on this straightforward assessment, stating in their own appendix that “we can now say with no doubt, there was no collusion.” That is to insist that up is down.

But call it whatever you like: The Intelligence Committee report shows clear coordination between Russians and the Trump campaign, though there is no evidence of an explicit agreement. The evidence the report lays out suggests Mr. Trump knew this at the time. Whether or not it can be proved that he ordered this interference or violated the law in doing so, the fact remains that neither he nor anyone else in his campaign alerted federal law-enforcement authorities, as any loyal American should have.

And remember: Mr. Trump tried this scheme again. The president was impeached for his efforts to invite foreign interference in the 2020 election, this time by Ukraine, again on his behalf. Part of that requested interference involved an attempt to smear Joe Biden. But the other part involved pinning the 2016 election interference on Ukraine rather than on Russia. Who was “almost certainly” one of the primary sources spreading that claim in the media, according to the senators’ report? None other than Konstantin Kilimnik.

There has never been any reliable evidence that Ukraine interfered in 2016; the Senate committee concluded as such, in line with all previous investigations.

Russia is now attempting to help Mr. Trump again this November, according to American intelligence assessments reported in The Times. For any normal president, that would be a top-of-mind concern, and he or she would be marshaling all available resources to thwart it. What has Mr. Trump done? On Sunday night, he retweeted Russian propaganda that the U.S. intelligence community had already flagged as part of that country’s efforts to skew the election.

On Monday, Miles Taylor, a former chief of staff at the Department of Homeland Security in the Trump administration, wrote that the president “showed vanishingly little interest in subjects of vital national security interest, including cybersecurity, domestic terrorism and malicious foreign interference in U.S. affairs.” He added, “the country is less secure as a direct result of the president’s actions.”

There’s no way to sugarcoat it. In less than three months, the American people could re-elect a man who received a foreign government’s help to win one election and has shown neither remorse nor reservations about doing so again.
