US President Donald Trump has defended Elon Musk, saying the billionaire is “terrific” and is “not profiting” from his work for the White House.

Musk has been tasked with slashing government costs by leading the Department of Government Efficiency (Doge), which is not an official government department.

Some of Doge’s moves are the subject of lawsuits, most recently after an attempted takeover of secure systems at the Treasury Department.

Trump allies and Democrats have been doing the rounds on US morning television, and Doge has been the major talking point.

Later on Sunday, Trump will be the first US President to attend the Super Bowl, one of the most watched events of the year in America.
