Former Chicago Mayor Rahm Emanuel (D) spent his Sunday suggesting Democrats do something genuinely novel if they win back Congress after the midterms: pass an ethics package instead of launching a third impeachment of President Trump.

Appearing on NBC News's "Meet the Press" with Kristen Welker, Emanuel made clear he still wants investigations. "I'm for the investigations. Hold this administration accountable, which is what the Republican Congress and Senate has refused to do," he said - before veering into a metaphor involving Williams Sonoma wedding registries and the Kremlin, apparently because the standard political lexicon simply wasn't up to the task.

Emanuel was referencing a ProPublica report about a Russian oligarch funding the wedding celebration of Donald Trump Jr. "They paid $170,000 for a wedding party. And nobody thought it was wrong," he said. "That tells you the sense of impunity that's operating."

Having established the impunity, Emanuel - also former President Obama's chief of staff during his first term - urged Democrats to "pass an ethics package." His reasoning was refreshingly blunt: "You're never going to get an impeachment. Then if you do that, you just basically proved all Washington is what the American people think."

Trump was impeached twice during his first term. So far in his second, Democrats haven't exactly rushed to try again, beyond a bid by Rep. Al Green (D-Texas) that several House Democrats voted down - a rare instance of Congress declining to do something.

Democrats do appear poised to recapture the House, with Decision Desk HQ forecasting 238 seats following this year's midterms. The electoral environment is friendly, weighed down for the GOP by the unpopular war in Iran, President Trump's poor approval rating and concerns about the economy. According to DDHQ, Trump's approval stood at 38.6 percent on Sunday afternoon, with disapproval at 59.3 percent.

The Hill has reached out to the White House for comment, presumably to a registry that remains conspicuously Kremlin-free.
