Howard Dean speaks at the DNC's meeting Friday.

WASHINGTON (CNN) - Hillary Clinton has canceled her speech before the Democratic National Committee as a result of the developments at her New Hampshire office, DNC Chairman Howard Dean announced.

“Unfortunately as some of you know, there is a hostage situation in New Hampshire involving a Clinton campaign staff person," he said. "The details are sketchy at this time, but understandably Senator Clinton is now dealing with this very difficult problem and she is not going to be able to join us today. And we will keep them in our prayers and hope for a resolution to this situation in New Hampshire.”

Clinton adviser Harold Ickes said no decision had been made yet on whether Clinton would go to New Hampshire. He said she is taking her cue from what police negotiators on the scene advise.

Meanwhile, two other presidential candidates - Sen. Joe Biden and Rep. Dennis Kucinich - commented on the situation in their speeches to the DNC.

"I heard the news about Hillary's headquarters," Biden said. "And I am sure like everybody here – I pray to God that it all works out right and I wish Hillary the best of luck as she heads to New Hampshire."

"At this time when one of our fellow candidates has to be concerned about her staff members - and we are in solidarity with Hillary at this moment when we think of what she is going through and what her staff is going through," Kucinich said.
