Rather than demand the extradition of Russian individuals named in the special counsel’s indictment for their personal involvement in election tampering, Trump invited Russia to interrogate the American intelligence personnel who had reached those conclusions. The president of the United States invited a hostile foreign power into the inner workings of our intelligence assessments and legal processes. Not only does that create a false equivalence between the rule of law in our country and in a country where political dissidents are shot in the streets, it would be a bonanza of sources and methods for Russian intelligence, improving their ability to subvert the rule of law and further foment bitter political divides in our country.

Conor Friedersdorf: Trump can’t brush Russian interference under the table.

I passionately hope Stephen Sestanovich proves right, and that the president’s overt alignment with a murderous dictator proves a turning point for Republicans in Congress. The president has moved beyond disgraceful. He’s now genuinely dangerous.

The early evidence, however, is not promising. Senator John McCain castigated Trump. “The president made a conscious choice to defend a tyrant against the fair questions of a free press, and to grant Putin an uncontested platform to spew propaganda and lies to the world,” he said. McCain would; he has been a voice of conscience on issues of freedom and tyranny.

Senators Sasse and Flake likewise objected; to their credit, that was also predictable. Even Representative Pete King tweeted, “Wrong for President Trump to deny Russian interference in election. No moral equivalency between US and Russia. Putin is a liar and Russia is an aggressor. No purpose in denying that.” It is not too late for Republicans in Congress to exercise their constitutional prerogatives and hem in an unfit president.

The Senate sits Republican by one vote (absent McCain); it could legislate against the president’s dangerous actions, as it did by putting sanctions in place against Russia at the start of the administration and passing a non-binding resolution supporting the NATO alliance.

Danielle Pletka: The endless anti-Trump outrage is counterproductive.

There is yet much more Congress can, and should, do. It should stop impugning the integrity of civil servants, particularly in law enforcement. It should legislate against presidential actions that damage national security. It should refuse to confirm nominees without extracting promises from the White House of compliance with the law. It should protect the Mueller investigation and ensure it has the resources necessary to continue its work. It should provide political penalties for breaches of political norms. It should ensure funds are expended with transparency and that the president’s financial dealings are exposed. It should reach across party lines to defend the rule of law. It should condemn the ostracization of journalists.
