Donald Trump didn't save the ethics committee. You did:

"As ethics experts from both the Bush and Obama administrations have written, the founders saw the so-called Emoluments clause as a way to stop corruption by foreign powers. If a president accepts any gifts and benefits from foreign nations, he faces the threat of impeachment.

Instead the newly-elected Trump claims, wrongly, that there is nothing to prevent him from being president of the United States and CEO of his company at the same time. “In theory I could run my business perfectly and then run the country perfectly,” he told the New York Times.

It takes real leadership to create a culture of ethics, and it takes very little leadership to destroy any semblance of ethics. It’s only natural that the House Republicans would follow Trump’s lead by treating ethics as some kind of low priority interference with their real business: business itself."
