Let’s start easy, with a handful of “Non-Lickspittle” moves, some of which have already been called for by Senate Democrats:

1. Fully implement the broad Russia sanctions bill passed last year, with a special focus on Mr. Putin and the oligarchs in his inner circle. Democrats on the Senate Foreign Relations Committee put some fresh ones on the table months ago. Now seems like a good time to revisit.

2. Hold hearings and compel testimony from the national security team that accompanied Mr. Trump to Helsinki, Finland. Demand details of any pledges made in the Trump-Putin private session.

3. Stop parroting the president’s line that the federal law enforcement and intelligence agencies are politically motivated, inept and generally corrupt. At the very least, House Speaker Paul Ryan should publicly call out his rowdier troops for pushing to impeach Deputy Attorney General Rod Rosenstein.

4. Call on Mr. Trump to demand the extradition of the Russians whom the Justice Department gained indictments for last week.

5. Take additional steps to protect the integrity of the coming elections from further Russian meddling. Significantly more money is needed, along with incentives for state and local election agencies to identify weak spots, erect firewalls and pursue other precautions. From what we already know about Russia’s invading voter databases, it is eager to make mischief.
