“Giuliani’s television appearances do not inspire confidence in his ability as a lawyer or as a public relations professional,” said Kathleen Clark, a law professor at Washington University in St. Louis. She said she could understand why the powerhouse law firm Greenberg Traurig, where Giuliani worked until last week, “would want to distance itself” from Giuliani’s on-air performance.

Norm Eisen, who served as President Barack Obama’s special assistant for ethics and government reform, said Giuliani hasn’t demonstrated the steady hand that “sophisticated legal consumers” demand.

“It could be good for Giuliani’s consulting and legal work if he were doing a better job,” Eisen said. “But no clients are going to be won over by the fact that he’s implicated Trump,” said Eisen, who chairs the left-leaning Citizens for Responsibility and Ethics in Washington, a nonprofit watchdog group that’s frequently challenged Trump for alleged conflicts of interest.
