Richard Wolffe Returns To "Countdown" (VIDEO)

Richard Wolffe returned to MSNBC's "Countdown" Thursday after a month-long absence.

Wolffe had generated some controversy over his appearances and guest-hosting stints on MSNBC and a perceived conflict of interest owing to his work with Washington public affairs for Public Strategies Inc.

Last month, Keith Olbermann said Wolffe would "not be appearing with us" until MSNBC could clarify his relationship with Public Strategies, and the network admitted error in failing to disclose Wolffe's ties to the firm.

Thursday night, Olbermann welcomed Wolffe for a discussion of Sarah Palin's book and her co-author Lynn Vincent, introducing him as "MSNBC political analyst Richard Wolffe, also senior strategist at Public Strategies, author of "Renegade: The Making of a President."
