Anyone hoping President-elect Donald Trump will fail in his upcoming second term is "rooting against the nation," John Fetterman said.
The Pennsylvania Democrat told ABC News he would not ever want a president to be unsuccessful, adding: "Country first. I know that's become maybe like a cliche, but it happens to be true."
Mr Fetterman's comments came with just under a month to go until the Republican is sworn in as president of the United States at his inauguration on 20 January.
