Sen. John McCain announced he will be a candidate for president of the United States during the taping of Wednesday night’s “Late Show With David Letterman.” The program will air tonight at 11:35 p.m. ET on CBS.

“The last time we were on this program-I’m sure you remember everything very clearly that we say-but you asked me if I would come back on this show if I was going to announce,” Sen. McCain, R-Ariz., told Mr. Letterman. “I am announcing that I will be a candidate for president of the United States.”
