A biographer says Donald Trump once told him that he informed second wife Marla Maples he was seeking a divorce by leaking it to the New York Post. President Trump now seems to be using Twitterto tell Republicans in Congress that he’s divorcing them, or at least seeking a trial separation, and for its own self-preservation the GOP Congress is going to have to find different living arrangements.

Mr. Trump has made common cause with the Congressional GOP in his first seven months on a few issues that have been his rare legislative successes— Neil Gorsuch to the Supreme Court and deregulation. But the lesson he seems to have taken from the Senate health-care failure is that he should distance himself from Republicans on Capitol Hill. No matter that he never gave a speech selling reform and even said amid the Senate debate that the House bill was “mean.” Thanks, mate.

Bashing Republicans won’t help him pass his fall agenda, but Mr. Trump may think he needs to protect himself politically by making Congress his foil. This would explain Mr. Trump’s recent gibes at Majority Leader Mitch McConnell for the Senate’s health-care failure. On Thursday he broadened the indictment to include blaming Mr. McConnell and House Speaker Paul Ryan, in advance, for trouble raising the federal debt ceiling when Congress returns in September.

“I requested that Mitch M & Paul R tie the Debt Ceiling legislation into the popular V.A. Bill (which just passed) for easy approval,” he tweeted. “They didn’t do it so now we have a big deal with Dems holding them up (as usual) on Debt Ceiling approval. Could have been so easy-now a mess!”
