Former North Carolina Sen. John Edwards announced Wednesday he and wife Elizabeth have canceled a visit this week on ABC’s "The View" because of the CBS News writers strike. Sen. Hillary Clinton (D-NY), Sen. Barack Obama (D-IL) and New Mexico Gov. Bill Richardson (D-NY) also said they would withdraw from CBS News’ presidential debate on 12/10, if CBS news writers go out on strike. The Obama campaign said in a statement: "If CBS News is unable to reach an agreement with its workers and they decide to strike, Barack Obama will not cross the picket line to attend the debate." "It is my hope that both sides will reach an agreement that results in a secure contract for the workers at CBS News, but let me be clear: I will honor the picket line if the workers at CBS News decide to strike," Clinton said.
