Republicans are dim, too, if they don't rein in Trump, whose "animus is almost pathological," warns Bloomberg's Robert A. George.
Trump's former transportation secretary has previously made a point of not responding to the ex-president's comments.
"He’s trying to get a rise out of us," said former U.S. Secretary of Transportation Elaine Chao.
Fox Business Network's Stuart Varney asked Trump's former transportation secretary if she had a response to his September slurs.
Donald Trump's comments about Chao and Mitch McConnell "could well cause violence," the Wyoming Republican warned.
“As you know, the president likes to give people nicknames," said Scott, who chairs Senate Republicans' campaign committee.
Asked if he had any reaction to Donald Trump insulting the woman he is married to, the Kentucky Republican simply responded, “No.”
The committee also reportedly interviewed former Transportation Secretary Elaine Chao and former Secretary of State Mike Pompeo.
Trump also reportedly mocked the senator's wife, former Transportation Secretary Elaine Chao, over her decision to resign in the wake of the Jan. 6 riot.
The potential ethics violations were sent last year to the Justice Department, which declined to investigate Trump's transportation secretary.
