“Well, I hope that he changes his mind again,” Sanders told reporters. “Mr. Trump has been known to change his mind many times in a day.”

Sanders, who is running for the Democratic presidential nomination, called Trump a “bully,” adding, “Well Mr. Trump, what are you afraid of?”

Trump and Sanders set the political world on fire this week by hinting that they might face off in an unprecedented debate before the California primary on June 7.

Trump said Friday he is no longer interested in participating.

Sanders elaborated on his hopes Trump would come on board with a statement Friday afternoon and said there are several television networks interested in making the event a reality. 

“There is a reason why in virtually every national and statewide poll I am defeating Donald Trump, sometimes by very large margins and almost always by far larger margins than Secretary Clinton. There is a reason for that reality and the American people should be able to see it up front in a good debate and a clash of ideas," the statement read.
