ABC News’ Jennifer Parker reports: Sen. Hillary Clinton is expected to appear and speak in person Thursday in San Francisco, California before 6,000 labor activists at the annual convention of American Federation of State, County and Municipal Employees (AFSCME).
"We were the strongest supporters of Sen. Clinton during the Democratic primary," AFSCME spokesperson Gregory King told ABC News.com, "and now Clinton is coming to thank us for our support and ask us to support Sen. Barack Obama."
Obama will speak to the group via satellite from Cedar Rapids, Iowa following Clinton’s remarks.

AFSCME endorsed Obama for President on June 19, 2008. The union group has 1.4 million members.
