Donald Trump was supposed to be a guest on Tuesday night’s episode of Jimmy Kimmel Live, but the Republican frontrunner canceled at the last minute because of a “political obligation” he could not miss.

“I’m dying to find out what this major political commitment was. Usually, it means he had to go on CNN and call someone an idiot or something,” Kimmel, who’s taping shows in New York this week, told his audience on Tuesday night. “Why did he cancel? We told him there were cameras here, right? Are Tuesday nights the night he volunteers down at the orphanage?”

Kimmel joked that he planned to give each member of the audience a basketball doused in cologne, so viewers “could fully experience what it would have been like had Donald Trump been here.”

Ever the optimist, however, Kimmel found one silver lining to the cancellation. “I will say, the good part about Donald Trump not being here is we don’t have to build a wall around Guillermo tonight,” Kimmel joked. One of Trump’s major foreign policy platforms is to build a wall between the U.S. and Mexican border.
