LOS ANGELES — Five days after being fired from his top-rated Fox News Channel perch, Bill O’Reilly used a podcast to express his dismay and vowed that “the truth will come out.”

“I am sad that I’m not on television anymore,” he said in an episode Monday of his personal website’s “No Spin News” podcast, available only to subscribers after this week’s free window. “I was very surprised how it all turned out.”

O’Reilly, who exited Fox News amid sexual harassment allegations that he has denied, said he couldn’t add much more “because there’s much stuff going on right now.”

O’Reilly’s remarks were the first since his exit on Wednesday, which took place while he was away on his vacation. He had issued a statement after Fox announced his departure, defending himself against what he called “unfounded claims” and saying he took pride in his 20-plus years with the news channel.
