The former president made his first post-presidential visit to a late-night show, albeit virtually, on Jimmy Kimmel Live! Thursday night to promote his new book A Promised Land. During their lengthy chat, Kimmel was able to get Obama to take a shot at his successor Donald Trump. Noting that Obama's book is 700+ pages, Kimmel asked: "Did you make it that long to make sure Trump never reads it?" Obama quipped in response: "I don't think it would have had to be 700 pages." Obama also joked about Trump possibly not leaving the White House. “Well, I think we can always send the Navy SEALS in there to dig him out," he joked. Kimmel also stunned Obama with a highly personal question, asking whether he and Michelle Obama had gotten intimate after ordering the raid on Osama bin Laden, leaving the former president flustered.
