ABC News' Bret Hovel Reports: Sen. John McCain, R-Ariz., will appear on "The Late Show with David Letterman" Thursday, three weeks and a day after cancelling an appearance there to suspend his campaign and work on congressional bill to bailout struggling financial institutions.
Letterman ridiculed the Republican nominee on his CBS show for several nights after that for pulling out of the interview.
"This is not the way a tested hero behaves. Somebody’s putting something in his Metamucil," said Letterman.
Letterman seemed particularly perturbed by the fact that McCain did not return immediately to Washington, as the late night host said he was made to believe. Instead, McCain appeared on the CBS Evening News with Katie Couric the night he suspended his campaign. He also spoke to Bill Clinton’s foundation the next morning in Manhattan.
Thursday’s visit will be McCain’s thirteenth time on the show.
McCain won't have the late night airwaves to himself this Thursday, Democratic VP candidate Delaware Sen. Joe Biden will appear on NBC's "Tonight Show".
