Evan McMullin, writing in the New York Times:
President Trump’s disturbing Russian connections present an acute danger to American national security. According to reports this week, Mr. Trump’s team maintained frequent contact with Russian officials, including senior intelligence officers, during the campaign. This led to concerns about possible collusion with one of America’s principal strategic adversaries as it tried to influence the election in Mr. Trump’s favor. On Monday, Mr. Trump’s national security adviser, Michael T. Flynn, was forced to resign after details of his communications with the Russian ambassador emerged.
Republican leaders in Congress now bear the most responsibility for holding the president accountable and protecting the nation. They can’t say they didn’t see the Russian interference coming. They knew all along.
Early in 2015, senior Republican congressional leaders visited Ukraine and returned full of praise for its fight for independence in spite of Russia’s efforts to destabilize the country and annex some of its regions. And in June, coincidentally just before Mr. Trump announced his campaign for the Republican nomination, they met with Ukraine’s prime minister in Washington — one of many meetings I attended as a senior aide to the House Republican Conference.
As the presidential race wore on, some of those leaders began to see parallels between Russia’s disinformation operations in Ukraine and Europe and its activities in the United States. They were alarmed by the Kremlin-backed cable network RT America, which was running stories intended, they judged, to undermine Americans’ trust in democratic institutions and promote Mr. Trump’s candidacy. Deeply unsettled, the leaders discussed these concerns privately on several occasions I witnessed.
Some also questioned Mr. Trump’s attacks on Hispanics, Muslims, women and people with disabilities, or his positions on entitlement reform, discretionary spending and national security. Others were unnerved by his volatile temperament, egoism and authoritarian tendencies. In public, they occasionally offered light criticism of Mr. Trump’s most objectionable comments, but mostly remained silent for fear of antagonizing his supporters.
As Mr. Trump campaigned, his consistent affection for Russia’s president, Vladimir V. Putin, and apparent defense of Russian intervention in Ukraine raised further concerns. In December 2015, on “Morning Joe,” Mr. Trump said of Mr. Putin, “He’s running his country and at least he’s a leader, unlike what we have in this country.” He also equated Mr. Putin’s murderous regime with the American government: “Our country does plenty of killing, also” — a remark he has repeated as president.
Suspect public comments like these led one senior Republican leader to dolefully inform his peers that he thought Mr. Trump was on the Kremlin’s payroll, suggesting that Mr. Trump had been compromised by Russian intelligence. Other leaders were surprised by their colleague’s frank assessment, but did not dispute it.
As Mr. Trump prevailed in state after state, the leaders came to terms with the possibility, then the likelihood, that he would win the nomination. During the process, most leaders had not endorsed a candidate and hoped that Mr. Trump would be stopped. By early May 2016, however, his victory appeared a fait accompli, placing them in an unenviable position. As senior leaders, opposing the outcome of the party contest was unthinkable.
Eventually, one by one, they all committed to supporting Mr. Trump, often simply saying they would support the nominee, conspicuously avoiding uttering Mr. Trump’s name. In a fascinating political metamorphosis, some even found reason to be excited about Mr. Trump.

Now the leaders’ worst fears seem validated. Mr. Flynn has become the third Trump team member to step down over Russia-related issues, following the campaign chairman Paul Manafort and the foreign policy adviser Carter Page.
This plotline is unlikely to improve of its own accord, and America’s security is now at stake. For Republican leaders in Congress, there is no more room for cognitive dissonance. Instead, it is urgent that they recommit to patriotic prudence. They should demand that Attorney General Jeff Sessions appoint an independent special counsel to investigate Russia’s assault on American democracy and Mr. Trump’s possible collusion with the Kremlin.
