This just in from the National Journal as Day Three of the Democratic National Convention is minutes away from its opening gave:

Sen. Hillary Rodham Clinton today told her delegates they were free to vote for Sen. Barack Obama during tonight’s nominating roll call, but she did not direct them to do so. “I am here to release you as my delegates,” Clinton told her supporters at the Convention Center in Denver. Many responded with shouts of “No, no.” She added, to cheers, “I am not telling you what to do.”

Clinton, who waged a sometimes bitter campaign with Obama through a long series of primaries and caucuses, said she marked her ballot for Obama this morning. “Many other people who sign their ballots will make a different choice,” she said, adding that whatever decision delegates make, “you are to be given the respect and recognition you have earned as delegates for the Democratic Party.”
