"It doesn't make sense to me that you are going to vote for Trump but you won't endorse him," CNN's host Chris Cuomo told Giuliani on Tuesday morning.
 
"OK, so I'll endorse him," Giuliani responded. "But I'm not part of the campaign."
 
Pressed again to leave no doubt about his support, the former mayor responded, "I'm Rudy Giuliani. I mean a lot in New York politics. I endorse Donald Trump — but I'm not part of the campaign."

The line of questioning came a day after Giuliani was pressed by Fox News anchor Megyn Kelly on why he was not endorsing Monday night. 

"Only because I'm not part of the campaign," Giuliani told Fox News. "I don't want anybody to think I am an official in the campaign, I'm part of the campaign, I take orders from the campaign."
 
The former mayor said there were some things he wanted to see change within the Trump campaign before he would fully endorse and noted he did not want to be on the campaign trail.
