A leading House Democrat is preparing a constitutional amendment in response to the Supreme Court’s landmark immunity ruling, seeking to reverse the decision “and ensure that no president is above the law.”

Rep. Joseph Morelle of New York, the top Democrat on the House Administration Committee, sent a letter to colleagues informing them of his intent to file the resolution, which would kickstart what’s traditionally a cumbersome amendment process.

“This amendment will do what SCOTUS failed to do — prioritize our democracy,” Morelle said in a statement to AP.

It’s the most significant legislative response yet to the decision this week from the court’s conservative majority, which stunned Washington and drew a sharp dissent from the court’s liberal justices warning of the perils to democracy, particularly as Trump seeks a return to the White House. Still, the effort stands almost no chance of succeeding in this Congress.
