Republicans are to drop a plan to gut the independent body that investigates political misconduct, after an outcry.
President-elect Donald Trump had criticised Republicans after they voted to strip the Office of Congressional Ethics of its independence.
“Focus on tax reform, healthcare and so many other things of far greater importance!” Mr Trump said in a tweet.
The proposal was dropped in an emergency meeting at the new Congress, unnamed lawmakers told the US media.
Mr Trump made cleaning up corruption in Washington a key theme of his campaign, and he ended his tweet with “#DTS”, an acronym for “drain the swamp”.
